I came across this new antenna, the TWAYRDIO RH 660S, mentioned in this Ham Radio Crash Course video. I have previously been recommending the TWAYRDIO TH770 antenna via this post. The RH 660S is a newer dual-band 2m/70cm telescoping antenna from the same company.

For Summits On The Air (SOTA), I generally take along such an antenna. The performance of any half-wave antenna on a handheld radio is always much better than the standard rubber duck. Although a 3-element Yagi antenna provides even better performance, it has to be pointed in the right direction. Sometimes, we will set up the RH 660 or TH 770 on a small vertical pole (actually a camera monopod with a homebrew BNC attachment). This allows us to monitor and work the band with an omnidirectional antenna without having to hold or point the Yagi. Much more convenient while sitting there eating lunch.

A key advantage to an omnidirectional antenna is that it is always pointed in the right direction.

The RH660 is available with the three standard connectors: BNC, SMA Male and SMA female. Make sure you pick the right one that matches your radio.

On our most recent SOTA activation, I did a quick comparison between the old TH 770 and the new RH 660 on 2 meters. The RH 660 seemed to perform ever so slightly better, but that was probably within the measurement error of the test. It certainly was not worse than the TH 770. I only did the comparison test on 2 meters, as that is the GO TO band for VHF SOTA. However, the antenna seemed to work OK on 70cm as well.

The packaging on the antenna indicates 3.0 dBi gain on 144 MHz and 5.0 dBi gain on 430 MHz. Do I believe those numbers? Not really, but they are probably close. (An ideal halfwave radiator has a gain of 2.2 dBi.) Note that the newer antenna does not have the magic tuning lump in the middle of the radiating element, which simplifies the mechanical design. This is the main advantage of the new antenna: no lump in the middle, resulting in a slimmer and sturdier design.

Summary

I am pleased with this new design, and I now recommend it as a good compact antenna for portable use. As with all telescoping 2m half-wave antennas, it is long and should be handled with care. Otherwise, you can poke someone’s eye out, break it in two, or snap the connector off your HT.

The RH660 antenna is available at Amazon for ~$17. At this price, why wouldn’t you have one in your backpack or Go Bag?

You’ve probably seen the messages about the ARRL push for relief from antenna restrictions by Home Owners Associations (HOAs). If not, take a look here. It is clear that excessively tight HOA restrictions are a significant barrier to getting started in ham radio.

ARRL has launched a nationwide grassroots campaign aimed at securing the passage of federal legislation that would grant Amateur Radio Operators the same rights to install antennas on their property as those enjoyed by users of TV antennas, wireless internet, and flagpoles.

The campaign, announced in an ARRL Member Bulletin on September 17, 2025, follows the reintroduction of the Amateur Radio Emergency Preparedness Act in February 2025 (see ARRL News 02/07/2025). The bipartisan bills — H.R.1094 in the House and S.459 in the Senate — are designed to prevent restrictive homeowners’ association (HOA) rules that currently prohibit or severely limit the installation of amateur radio antennas, even when such antennas are hidden in trees, placed in attics, mounted on vehicles, or look like flagpoles.

While the ARRL is pushing for this bill, I have not seen much written about what is actually IN the bill. You can read the entire text here: HR 1094 – Amateur Radio Emergency Preparedness Act.

But here’s my summary. The bill requires that specific amateur radio antennas not require approval from HOAs or similar organizations:

• Antennas that are 1 meter or less in diameter
• Flagpole antennas, not to exceed 43 feet in height
• Wire antennas – minimally obtrusive wire antennas
• Vertical antennas – not to exceed 43 feet in height

Note that this does not mean you will have the right to put up a 60-foot tower with multiple large antennas on it. Some folks are probably disappointed in the limited nature of this bill. My view is that it is a reasonable accommodation to basic ham radio operation, very reasonable for urban and suburban environments. If you want to build the ultimate contest station, you’ll need to buy some rural property. This ARRL page provides some background on why this bill makes sense.

I am somewhat surprised by the 43-foot height limit for vertical antennas. This is apparently a carryover from previous ARRL legislative attempts. I would settle for something shorter than this…but what the heck. For reference, a quarter-wave vertical for the 40m band is about 33 feet high.

I think the ARRL has lined up the legislation, the lobbyists, and some Congresspeople to push this through. Can we get this passed? I don’t know, but I suggest we all get behind this by making our voices heard in Congress. The ARRL has made this VERY EASY to do. Just go here: https://send-a-letter.org/hoa/

That’s my view. What do you think?

Joyce/K0JJW and I did a SOTA activation with Mike/KE0PWR on Aspen Ridge (W0C/SP-084). It turns out that Mike’s wife, Laurel, has a YouTube channel, so she shot some video of our adventure. Keep in mind that her channel is not focused on ham radio, but has a more general audience.

Some time later, Mike did a SOTA activation on his own with Laurel capturing the story via video. This was on Wander Ridge (W0C/SP-042), one of my favorite summits near the Continental Divide Trail. Yes, it was windy on top. I made a cameo appearance via 2m FM. Short Buena Viking plug at the end (one of my favorite local restaurants).

And finally, here is another activation with Mike on South Peak (W0C/SR-111), near Weston Pass. In this episode, Mike demonstrates how the signal disappears if you lay the Yagi antenna on the rocks. I make another guest appearance via 2m FM.

Laurel plugs the PBJ Bobo’s, which are now my favorite hiking snack. (I am not addicted to these things. I can stop eating them anytime I want.)

Great job, Mike and Laurel!

The post Laurel Makes SOTA Videos appeared first on The KØNR Radio Site.

On August 18, I activated Mount Peck (W0C/ SP-053) with Steve/K5SJC, which put me over the top of 2000 activation points for SOTA. This is commonly known as 2x Mountain Goat or Double Mountain Goat. (Joyce/K0JJW was out of town, leaving me unsupervised for a few weeks.)

Steve, thanks for doing Mt Peck with me, it was fun! Joyce and I had great fun activating it back in 2017, and it was good to return to it. The summit is near the Continental Divide Trail, accessed from Monarch Pass, so it is an excellent hike on top of the world. The coolest thing about this summit is the nice rock that served as a gear table (see Steve’s photo above.) No bending down to pick up my backpack or equipment.

I tend to see the Mountain Goat Award (1000 points) as the primary SOTA award, establishing the SOTA activator as serious about the program. Anything beyond that is just more points. But still, 2000 points is a milestone worth recognizing, and it caused me to examine my SOTA log in retrospect.

Here are my stats for SOTA activations:Thanks to all of the chasers who made these activations possible. Here are my top chasers:

Here are some fun facts I have from reviewing my log. Currently, I have 2005 activation points. If you ask the SOTAdatabase for my 2m log, it also shows 2005 activation points. This is not quite right in my view, because it counts all activations with points that have at least one 2m contact included. That is, not all activations had four 2m or VHF contacts. In reality, I have 9 activations (corresponding to 41 points) that used HF to get the required four QSOs (for points). This means I need 36 more 2m-only points to get a pure 2x VHF Mountain Goat, untainted by HF QSOs.

People wonder how often Joyce/K0JJW and I get skunked on a summit using only VHF. Out of 346 activations, I’ve had 20 times falling short of getting the minimum four QSOs (5.7% of the total). I basically never fail to activate a summit because Joyce is usually along, and we work each other (outside the activation zone) to qualify for the activation, but not the points. Sometimes we anticipate that a VHF-only strategy is going to be a problem, so we take along HF gear to make up the difference. This usually happens in a rural area with low population density or in some other remote location such as American Samoa (KH8). Sometimes, we’ve made an extra effort to arrange for capable VHF stations to chase us. Good examples of this are Mount Ojibway and Capulin Mountain. Finally, sometimes we just accept the likelihood that we will come up short on VHF, but do the VHF-only activation anyway.

I’ve written a lot about how to optimize your VHF SOTA activations on my blog. In particular, see The Truth About VHF SOTA. SOTA is a fantastic and versatile program that can be adapted to your particular interests. Keep having fun with your kind of SOTA, whatever that is!

Special thanks to my spouse, hiking partner, SOTA enthusiast, and favorite radio amateur, Joyce/K0JJW, for joining me on these many SOTA activations.

The post Another SOTA Milestone: 2x Mountain Goat appeared first on The KØNR Radio Site.

I’ve been having fun with mountaintop VHF ham radio for decades, way before Summits On The Air (SOTA) was a thing. It is an activity that I enjoy very much during VHF contests, Parks On The Air (POTA) activations, SOTA activations, and just goofing around in the mountains. Most of this activity has been on the 2-meter band, but any frequency above 50 MHz can be fun.

My philosophy with ham radio is to have fun doing ham radio things and tell people about it. If they think VHF SOTA looks like fun, other hams may try it. At the same time, I want to be open about the challenges that may be encountered. Doing SOTA activations using just VHF can be difficult, even frustrating. (This is one of the reasons I like doing it.) So this post is a cautionary tale, focused on three essential principles.

1. VHF SOTA is easy to do, except when it’s not

A VHF SOTA activation can be as simple as taking a $30 handheld radio on a hike up a summit and making a few contacts on 146.52 MHz or another simplex frequency. The radio is compact, lightweight, and completely self-contained, ready to go! This is arguably the easiest way to do a SOTA activation if the summit is near a populated area.  For example, Genesee Mountain (W0C/FR-194) at 8284 feet overlooks the greater Denver area, so hike to that summit and you should have plenty of stations to work on 2m FM.

Now, try that same approach in a more rural part of the state and you may run into trouble. This is when VHF SOTA is challenging and potentially frustrating.

Which leads us to the second important principle…

2. You need to have chasers within range to contact

This is obvious, but you do need stations that are within range to work. This becomes more difficult in areas that have low population density. There may not be many radio hams within range of your chosen summit; they may not have 2m FM gear, they may not be listening to your frequency, and they may not even have the radio turned on.

Before activating a summit, consider the likely range and how many chasers might be around for you to contact. Take, for example, Aspen Ridge (W0C/SP-084) on the west side of South Park. The hike up is easy, and the elevation is substantial at 10,740 feet. The map shown above has a circle with a radius of ~25 miles, which is a conservative rule of thumb to get us started. Making radio contacts within this radius should be a slam dunk from this elevation, but it does depend on the actual terrain.

From the map, we can see that we should be able to work stations in Buena Vista and Salida, which are small mountain towns with a corresponding small ham radio population.  Some of these folks make it a habit to monitor 146.52 MHz to see what activity occurs on the calling frequency, which helps. But it helps to get the word out to the target audience that you will be on the air. The basic idea is to “send invitations” for your planned activation. The local radio club (Chaffee Lake Amateur Radio Association) has a groups.io list, so you could drop an email message there. If you know some of the hams in the area, you can always reach out and ask them to be listening for you. It is always good to post an ALERT and then a SPOT on SOTAwatch because some chasers may see that. Also, keep an eye on SOTAwatch for other SOTA activators that are on other summits.  During the summer months, it is common to encounter tourists, campers, hikers, or off-road enthusiasts on 2m simplex.

Looking at my Aspen Ridge logs, I see that I’ve worked K0MGL at his home station near Florrisant, at about 60 miles, with some mountains in the way. So the 25-mile radius shown on the map is quite conservative. (Much longer distances are possible.) Now, I probably would not be able to work K0MGL with just a handheld radio and a rubber duck antenna.

Which leads us to our third and final principle…

3. Every decibel of signal strength matters

VHF radio often gets described as being limited to “line of sight,” which is a helpful model but one that is incomplete. (See The Myth of VHF Line of Sight.) I often make VHF contacts beyond line of sight, bouncing signals around the mountains without knowing the actual radio path. These VHF SOTA contacts happen at the fringes of radio coverage. That is, there is just enough signal to complete a contact, but small changes in signal strength can make the difference between success and failure. So you should optimize your station as best you can.

First up is ditch the rubber duck antenna and get an antenna that is a half-wave in length on the 2-meter band. See A Better Antenna for Dualband Handhelds. Make sure it is a half-wave and not just one of those extended rubber duck antennas that are a quarter-wave. Those work a little better than the typical rubber duck, but the half-wave is far superior.

Another half-wave option is the roll-up J-pole antenna, such as the N9TAX Slim Jim antenna. (There is a slight difference in construction between a J-pole and a Slim Jim antenna but they are so similar, I consider them the same.) You can purchase this type of antenna already assembled, but it also makes for a fun project to build one from scratch. (Just search on the web for “2 meter j-pole antenna plan.”) You’ll need some way to support this antenna, such as a non-conductive pole or a rope strung from a tree.

The next step up in antenna performance is to add additional gain and directivity. I use the Arrow II 2m Yagi antenna, which provides about 6 dB of gain over a half-wave radiator. I normally just hold this antenna in my hand, but you can also set up a mast to support it.

Another option is to increase your power level. The typical HT puts out about 5 watts but a mobile radio can go up to 50 watts, a 10-dB improvement. While antenna improvements help on both transmit and receive, increased transmitter power only makes your transmitted signal stronger. However, if the other station is also running 50 watts in a vehicle or at home, more power from the summit tends to balance things out.

The key point here is that even a few decibels of improvement can yield more radio contacts.

Wrap It Up

So there we have it, three important principles to keep in mind when pursuing SOTA activations using VHF. I have had a ton of fun doing this, but I also know it can be frustrating. The most fun occurs when I make a long-distance contact that I did not expect. (My best DX from a SOTA summit using 2m FM is 245 miles.) Keeping these principles in mind helps to set expectations while providing some ideas for improving your odds of success.
