I was reading my most recent post and something clicked.....and it was not a good "click". I looked at the posted SWR chart from my 44-foot antenna experiment and the numbers looked very familiar! Somehow I copy and pasted the numbers from the 41 foot SWR results and reposted them for the 44-foot experiment. Below are the corrected results for the 44-foot Endfed wire.
Band Freq SWR
80m 3.500 8.4
80m 4.000 9.0
40m 7.001 4.6
40m 7.060 4.6
30m 10.100 4.6
30m 10.150 4.6
20m 14.001 2.1
20m 14.060 2.1
17m 18.068 2.3
17m 18.168 2.3
15m 21.001 3.1
15m 21.060 3.1
SWR without a counterpoise:
Band Freq SWR
80m 3.500 6.8
80m 4.000 6.1
40m 7.001 3.5
40m 7.060 3.5
30m 10.100 4.6
30m 10.150 4.6
20m 14.001 1.4
20m 14.060 1.4
17m 18.068 2.0
17m 18.168 2.1
15m 21.001 3.1
15m 21.060 3.1

Hello Mike, I would not be satisfied with this kind of SWR. Except may be for 20m. However it might be good for a all band endfed. After all it is a antenna that is a compromise and you really need to use a antenna tuner. However I think there are better alternatives. You might read the ARRL antennabook for instance to get better ideas. And remember that a antenna you build yourself is most times working much better and much more satisfying! Good luck, 73, Bas
Good morning Bas, yes it's true the Endfed is a compromise antenna and I do use a tuner with it. I will have to sit down and look into other antenna ideas and as you said building one can be very rewarding. I just have to figure out with the lay of the land that I have what antenna will work with the room that I have.
Thanks for your input Bas it's always welcomed.
73,
Mike
