Please dont be rude to fellow hams.
Thats personal, Stop it immediately.
If that is not retracted I will push to have your account barred on here..
If that is addressed to me, what is there to retract? Rege has been insulting me and lots of other posters, and has been posting technically incorrect information about how antennas work on here for several years.
Then both of you stop it!
We don’t want to listen to diatribe and personal differences...
Let’s please be civil
Happy new year to all these wonderfully eccentric (me included) antenna nuts on this forum
Right now you hijacked the OP's thread and you're making more "noise" than Rege and Mike.
We have moderators here, let's them to do their job properly when needed.
Look, this antenna works within the limitations of the space I have. Here's the proof:
All I'm asking for is advice on how to improve it. I already have plans to raise the height, I'm just keen to know if feeding it from the remote end is worth the effort or not.
John, here is a wide sweep of the Swr relative to 2450 Ohms of a 144.6 ft horizontal wire 35ft agl over average dirt, fed 9.4 ft in from the wire end (the prototype EFHW wire antenna):
Notice that the step from 40m to 20m is a bit wide, but the steps from 20m to 15m and up are just right. Adding a capacitor at the center of the long wire makes it possible to almost perfectly center the Swr minimums on each band...
And adding a loading coil brings in 80m ...
My antenna is a 63 feet wire attached to a 6 feet post over my roof and the other side to a 12 feet post. Using a 9:1 balun at feed point done by me. My record is Japan from South Texas 10930 km distance on FT8 at 20m band.
