I just put up a Hy Gain Hy Tower which is 53 feet tall and is liner loaded
somehow to be a 1/4 wave on 75 meters. It works quite well with a modest 1000ft
ground field. I am considering adding a second vertical and would use a simple
Christman feed system to phase the two.
My question is: Do I have to have another very similar short vertical such as
a Hy Tower or could I use a full size 1/4 wave vertical for the second antenna
spaced 1/4 wave away with a second ground field just like the hy tower has. I
have some Rohn 25 and long mast which could get me to 62 feet high and use
fiberglass rod insulators at the base of the Rohn.
