You have a horse?
That video ^^ clarifies everything.
The 80m SWR bandwidth is way too wide for the antenna to be efficient. It has series resistance due to the relatively poor conductivity of the "horse fence" wires, which of course is dissipative and will make the antenna more resistive and less reactive over a wider part of the band than could be achieved using excellent conductors like copper wires.
I'm not sure the guy in the video actually understood that, but it's evident.
Another "neat" thing about using this stuff is that, as the little wires break, they may stay in contact and form little rectifiers that will give you the chance to hear your local BCB stations all over the dial.
27 people love them!
But what about 50 million Frenchmen?
Or three headless HORSEMEN!
Well I make them for sale on both 75/80 Meters and 40 Meters. Been shipping all over the nation and not one single complaint. I don't know where WB2WIK got his info or measurements, BUT they seriously disagree with my measurements. At 60 feet I read 7.3 ohms (that is not high resistance). For more info look in the "Made for Hams" section of this website.
You have to listen closely to the video. The SWR numbers he is quoting is AFTER going thru a tuner. The numbers are meaningless, other than the fact he seems to have a poor tuner if he can only get an SWR of 1.3 on the band edges.
Is that ac resistance or dc resistance. How did you measure it with the antenna at 60 ft?
I see some more info on the other forum, as mentioned.
Resistance is not pure and simple. If you measured that with an analyzer, then you either have an antenna problem or a bad measurement.
Stainless steel has no effect on corona.
You're right, I didn't listen closely enough. I have a really good manual tuner (ATR-30) that can match a 36" long clip lead on 80m and the damned thing will make contacts -- I've demoed that. At 100W, it doesn't even arc the tuner.
I agree. The "atmosphere" around the antenna (typically at the ends) does.
