Default 360 ft. wire antenna 22db gain?


I remember reading on some internet site about some end fed wire antenna that was around 360 ft. long and it showed 22db gain. Some hamster's site.
Does this ring a bell with anybody? Id really like top find it again.

Sure it might be possible at many full wavelengths long at a given frequency and terminated at the end.

I would be highly directional and narrow in the direction of the far end of the wire though.

I believe Cebik covered end fed wires. That's the site you want for wire antenna info.

Yeah that might be possible but it still sounds pretty high. Longwires of this kind are also called Beverage Antennas and would need to be in a straight line and will be directional straight off the end. Guys who live out in the plains on a big piece of flat land will have several of these and switch around to obtain TX in the different directions.

360 feet and 22 dB gain?? Maybe on 2m but NWIH on any HF band. My 600 foot antenna only had about 9 dB gain on 20m and that was directly inline with the antenna wire.

While it's possible, it's also very frequency dependent, as already posted. The part that's typically left out, the frequency/shape/circumstances is the 'kicker'. Might be possible on '440, but not on 160 meters. If you should happen to find that site, it'd be interesting to read it. - 'Doc

I think that is what I read, 10 wavelengths long gives about 10 dB gain straight off the end...

it was a while ago, I still cant find the site. I really wish i could even remember what band it was for. I guess from what you guys are saying is its not possible on 27mhz so I guess i will have to just put it out of my mind...lol
it really sounded like something when I read it
