You are probably right about the ground loss. In a balanced system the
dominate loss will not be ground loss but you can't escape higher Q with short antennas. I'd prefer a vertical antenna with an attached tuner if possible. But it is more complex and more costly. 73 Bill wa4lav At 02:17 PM 6/2/2004 -0400, Tom Rauch wrote: > It turns out that the shorter an antenna is relative to a > wavelength is, the higher the Q of the resonant antenna system (antenna, > transmission lines, coils, inductors and tuner) must become to effectively > radiate RF energy.
