In the park with 5 watts, KX3 and new Endfed antenna

My outdoor shack 
I had this past Thursday off work and it was time to take my KX3 out on the trail again. In my last outing I used mono band whip antenna that was mounted on my bike along with a counterpoise. After giving this setup several tries I came to the conclusion that it was time to look at another setup option. I ordered the Endfed 40-6m antenna and it came in last week and it was now time to give it a go. To get the Endfed 40-6m antenna up on a tree branch I used an idea that was emailed to me by a fellow ham. I purchased some golfballs, closed ended "eye" hooks that are threaded on one end,  carabiners and rope. The "Eye hook is screwed into the golfball, one side of the carabiner is hooked onto the eye  and the rope is loop knotted and the other side of the carabiner is hooked onto the rope loop. I chose to use  a double sided carabiner at both ends of the antenna as it allows me to fast connect and disconnect without playing around with knots. I think using the golf ball is great as it has some

weight to it and is smooth on all sides allowing it pass through leaves and not getting hung up on branches. This method worked great for me and I was able to have good control with regards to placing the golfball in the tree right where I wanted it. Once the rope was in the tree I pulled the Endfed antenna up into the tree and got down to working the bands. When using this style of antenna I was informed that an antenna tuner is a must but I wanted to check out the SWR without using my tuner.
10m                    Frequency                    SWR
                           28.020                          3.8
                           28.060                          3.8
                           21.020                          2.9
                           21.060                          2.9
                           14.020                         3.8
                           14.060                         3.8
                           7.020                           8.4
                           7.040                           8.4
The antenna was mounted in a sloper configuration the high end at about 20 feet off the ground and the other end ground mounted. The tuner in the KX3 was able to bring all bands but 40m to a flat match, I was able to get 40m down to 1.5. The bands were very quite but I did spend some time
Anchor point 
calling CQ with the goal of checking the Reverse Beacon Network when I got home to see how my signal faired. I was not heard by any European stations but I was spotted on all bands by stations south of the boarder. The Solar conditions have not been all that great lately so I was very pleased with these results. I plan on heading out again on Saturday morning and this time my plan is to try to get the antenna higher up so a portion of my antenna is not at ground level. Since the weekend is here and I hope the bands will be more busy maybe a contact or two would be nice as well.

    Although the tuner will help, the antenna still have over 8:1 SWR on 40m. Would have been good if knew how long the slopper wire was and if used a balun. More was said about the golf balls.

  • Mike VE3WDM:

    Good morning Ron, thanks for taking the time to stop by and comment. With a name like Mike Weir (Canadian Pro golfer and green jacket holder) maybe that’s why more was said about golf balls in the post….:)) Having said that the golf ball does get the rope in the tree and the rope gets the antenna in the tree so really in my case no golf ball no antenna placement and thus a very short outing in the park……..there I go getting side tracked with golf balls again…….:)) As for the antenna the details were mentioned in my previous post and I should had put a link to that post. Here is a link to the actual antenna that I purchased with the details you are asking about.
    Have a great long weekend Ron.

  • Frank ON6UU:

    You did not mention the use of a radial, nor did you say how long the coax was.
    With an end fed you need a radial or a long coax. The coax will act as radial when no radial is presented.

    The radial can be clipped on the PL plug if no attachment point is at the balun.

    Give it a try.


  • Mike VE3WDM:

    Good morning Frank, the coax is 35 feet long as recommended by the maker of the Endfed 40-6m antenna. I can try adding the radial and see how that works as well.
    Thanks and 73,
