The vhf quad is a fascinating idea. Depends on your resources as far as
HF. The g5rv is a fine antenna, but it won't work below 3.5mhz unless you
double it to 202 feet for the inverted vee. Do you need an antenna that
won't need a tuner?
I feed 180feet of inverted Vee with 85ft of 450 Ohm twin lead and think it
is the best HF antenna I have ever used for work between 1.8 and 30mhz
