Hello all. I've always been under the impression that one had to have a 100' or taller tower in order to shunt feed it for 160m. Therefore, for years I've been fooling with long wires, random wires,
QSL on all Jim. Purchase Jeff Briggs, K1ZM's book from the ARRL titled "DXing on the Edge, The Thrill of 160 Meters" In it you'll find all the info and hints to shunt feed your tower. I did the same
Also Jim, you'll need something to receive on. The shunt fed tower is a vertical and you'll get all sorts of noise. There's a website that has a compendium of lowband beverage, pennants, flags, delta
Jim - Your personal e-mail bounced for some reason, hope you get this reply through the reflector....... Hi Jim, Yes, it can be done! I've had great success with the shunt fed system on my 40 foot to
Jim: I agree with Phil's recommendations on Jeff's book. You can get it from ARRL. I based my Trylon 64's shunt feed on Jeff's design. The key is to have something as a capacitive load at or near the
Yes, but if you get it from ARRL, then you have to PAY for it. Oh, wait, the ARRL as capitalist pigs thing is on another reflector. Sorry. 73, kelly ve4xt -- Original Message -- From: "EUGENE SMAR" <
Aren't radials also needed to make the shunt fed tower work efficiently? If so what would be the correct length and how many for a respectable installation? Julio, W4hy
The more the merrier, 30 minimum. Length not that critical but 1/4 wavelength at 130 ft. is theoretical best. Most recommend 60 radials and broadcasters go with 120. Last year I have about 30 down (p
I agree that a lot of radials are desirable. I now have 32 each longer than a quarter wavelength, BUT at my previous location on a tiny city lot I had two(2) laid alongside my sprinkler lines snaking
YES. IF you can get 1/4 WL (or more) then 30 to 60 radials is beneficial. IF you are limited to 1/8 WL long radials, there is virtually NO benefit above 15 radials. Tom N4KG _________________________
Julio: Yes, radials are needed. For my shunt-fed tower I have only 7 radials, only five of which are over 100 feet long. The other two are 30 feet long. BUT - this tower has a pretty decent lightning
You have a problem with capitalism ?? not near as much as I do with socialism... -- Original Message -- From: "Kelly Taylor" <ve4xt@mb.sympatico.ca> To: "EUGENE SMAR" <spelunk.sueno@prodigy.net>; <kb
OK then please explain why hy-gain in their manual for the 14AVQ has a table for optimum ground system configurations as radials 16 24 36 60 90 120 lengthin wl 0.1 0.125 0.15 0.2 0,25 0.4 feed point
Whether or not a radial density is enough by count depends on the "aperture" that exists between adjacent radials at the ends, as expressed in a fraction of a wavelength at the frequency in use. If t
Perhaps I should have said there is only a very small benefit to having more than 15 radials IF they are equal or less than 0.125 WL long. THE definitive work on radial systems was published in the J
