The F12 height is coincidental - N6BT's crank-up went to that height.
He was trying to make points about free-space gain versus the real world
(including ground reflection gain), and to clarify the difference
between dBd and dBi.

no one height is best for everything so put up a whole bunch of them at

When choosing a height for a beam is 1/4 wave above ground at the lowest frequency

Why that height? At 20 meters is 100' a lot better than say 60'? I am talking
about relatively flat terrain. I see Stepp-ir makes a beam that even has a 80
meter dipole in it. Would that workmuch better on 80 than a wire dipole at an
equal height? I have never had enough land to put upmore than 50' bit nest year
I might have over an acre and be able to go much higher. I just wonder how high
when you spend more to go higher than it is worth? If I had the room for a wire
dipole to run any direction, what would be the best choice from central Texas
considering being in the center of the country east/west wise? I want to get
the best bang for my buck! wb5oxq
