|Failed Hy-gain tape dipole|
Good Saturday afternoon readers and sorry for the tardiness with regards to finally getting around to part 3. Work has been very busy and not much computer or radio time! In this part I am going to look at the antennas I have used and I have used a lot of different configurations. I had some responses from those who live in condo townhouses I too have lived in a condo townhouse and had great success. Most townhouses up this way are of wood construction which is good news for the indoor antennas. If you have a multilevel townhouse you most likely have access to an attic. There may also be a back deck and or a small to medium backyard.
Let me begin by saying this segment on antennas assumes you are looking for something that is either hidden or looks like something it's not.
Most (but not mine) town homes have a garage and driveway to-which you park a car in. I have found a very simple way to get on the air is to put an antenna on your car and run coax out to it. Now having said that you don't want to run around town with a huge antenna on your car (maybe you ...but not me) There are many fast connect/disconnect mounts on the market. As for the antenna I have seen and did have a multi-band HF antenna. I did operate my home HF radio with a multi-band antenna.....yes I did say I had no driveway or garage but more on that in a minute. The antenna I used was something similar to the Comet UHV-6
mounted on my car. There is also the Hustler triband
adapter to allow 3 Hustler resonators to be used at the same time. With these types of antennas or similar ones you can run coax out to your car in the driveway connect to the antenna and your on the air.
In my case my townhouse at the time did not have a driveway or garage it was a common car parking lot. So what I did was I buried LMR 400 in plastic tubing out to where my car was. I terminated the coax to an SO-239 in a small plastic box. The box was in a small bush and unseen. When I wanted to go on the air I connected a small jumper of coax from the box to my car antenna. I was able to use this for about 3 years.
If you have an attic and I did in one of my town homes the best antenna for me was the Alpha Delta DX-EE.
I mounted this antenna in my attic is a "Z" configuration. To mount it I used stand off's for electric fences. This antenna was very close to the roof and other wood 2x4 rafters but surprisingly I had no real issues with SWR. My Elecraft K3 radio has a great tuner in it when needed.

Another antenna configuration I tried in my attic was two mono band whip antennas set up as a dipole. This antenna was tricking to mount in the attic as it was very rigid and required room. It worked well but do to the space this antenna needed I was only able to get two separate

antennas of this kind in the attic.

One antenna I had and tried in the attic but could not get it to work was the High Sierra sidekick antenna.
I tried various ground radial configurations but could not get it to tune at all.
I did end up mounting the High Sierra sidekick antenna in the backyard close to our deck. It was in a very hard spot to see and I was able to remove the antenna when not in use and bring it in the house. I was able to conspicuously bury some radials and was able to get a decent SWR.

Because our condo town home was mainly wood construction I was also able to setup my Alex Loop
in the living room by the patio sliding glass door and make some decent contacts.

Another failed antenna for me was the Hy-gain tape dipole and I am not sure why it did work and the DX-EE did but it was worth a try. I had this antenna for some time so there was no money outlay but it just did not want to tune. Part 4 will be dealing with Ham radio in a condo apartment building and how I have successfully gotten on the air for the past 6 years.
