No easy answers here...however the ARRL Handbook, and the ARRL Antenna Book
have several excellent chapters on this topic. Interesting reading, which it
runs from basic to complex, but the concepts and graphs are easy to
understand and really summarize the variables based on traditional antennas.
If you are looking for best bang for the buck, this reading will really help
you make the right decisions. Well worth the investment to buy new or used
copies, might even be at your local library!

Subject: [TowerTalk] How high is enough
When choosing a height for a beam is 1/4 wave above ground at the lowest
frequency enough? 1/2 wave? I see Force 12 rating the gain on their beams
at 74'1".
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
