- got a question..if using a 5/8 wave vertical should the radials also be 5/8 wave long i guessing yes they do...John K1GUN _______________________________________________ 160 meters is a serious band,

- Yes, As current radiation is raised in the vertical, longer radials are needed. Horizontal antennas are seldom used on 160 meters and below. The up to 6db ground reflection for horizontals up 1/2 wav

- OK, I'll bite... Why would you put up a 5/8 wave vertical? Have you modeled this dog? Now, I suspect you are talking about an inverted L - as the 5/8 vertical is 340 feet... This is an even bigger

- If you are asking about a monopole with elevated radials the radials should be 1/4 wavelength. If ground mounted with radials on or in the ground the length is not that important. The feedpoint resis

- I keep seeing this statement on various reflectors, but my tests on 1/4 wave and 1/2 wave verticals show that a 1/2 wave vertical with essentially no radials works as well as a 1/4 wave vertial with

- Not necessarily. My elevated radials on 160m are 53m long and that vertical is giving outstanding results. 73 Peter If you are asking about a monopole with elevated radials the radials should be 1/4

- Only a nibble, not a bite, The question had to do with using a 5/8 wave vertical and radials. In early days of AM radio, and I have spent most of my work life in Broadcasting Engineering, a 5/8 wave

- Hi Bruce, Well, it is horses for courses... The biggest problem for the DX oriented ham with a 5/8 wave will be the very high, and very big (only -5dB) secondary lobe, bringing in a ton of monky chat
