I was wondering if it's possible to shorten the radials from the standard 1/4 wavelength to another value, a smaller one. For example, in a 20 meters antenna, which is the best value of length for shortened radials or, in alternative, until which value is possible to go to without superlosses?===============================
Thanks in advance
It is my understanding that when radials are on the ground or buried
,their length can be any hence also shorter than 1/4 wavelength ,but
when very they are very short ,more of the same will give an improvement
especially when on dry ground.
When radials are above ground like when part of a vertical antenna
system fitted on a roof the quarter wave radial(s) ,at least 1 for each
band , are required ,since then they are 'the other half' of a dipole.
