K6SE was the first guy I saw doing this - with much shorter towers than mine. Somewhere in my files I have a copy of a four-page letter Earl sent to K2UU describing in detail the K6SE phased towers

Anybody on this list have a Rhombic for 160M? W1AW used to use one for bulletins and code practice on 160M but I think it came down years ago (1989?) They come in here literally against the pin which

I would think that with optimized F/R for your Beverages that at least one path would be somewhat quiet. They do indeed sometimes help reduce the QRN from some thunderstorms, particularly if they are

I dont see anything from then that disagrees with what I said today Mike, QRO in those days was a smaller ratio from what is daily these days. There are even a couble of super QRO SWBC stations owned

Those Alpha 77's, DX or SX went thru the Nye tuners shown and they were maxed out at around 4KW. The rack stuff was old school with glass tubes and mercury vapor rectifiers and took a lot of room for

I think this topic has gone from talking about actual radios and antennas and the merits and folklore about each, to disrespecting people. I actually thought it was kind of neat that as a 12 year old

The only way many of us can learn about the big names of years gone by is to listen in on discussions like these; Yes, but right here on Topband we have many current-day worthy replacements for them

This subject has been discussed here plenty of times in the past, and the consensus has always been that trees and other foliage near a 160m antenna has a negligible effect on the transmitted signal.

Seldom mentioned and worth repeating. The L has a bit of high angle radiation which can be useful at times. The T cancels it. Carl KM1H That's exactly what I was thinking. Top load it and forget abou

Assuming that sufficient tower height was available, guy wires are insulated or broken up into short non-resonant sections. Tower face is 12 or 18". Start at 1/4 wave up with a 1/4 wave ground plane

Youre getting confused Charlie. 1. My query was about a theoretical installation and not band specific. Maybe I'll try using the 600' UHF TV tower on the next hill over if there is a chance it might

I would expect that after X number of elevated radials it becomes moot. Height and ground conductivity determine the actual number. For my poor ground and 20' elevation it was somewhere around 24 bas
