Tim: Go to the Heights website: www.heightstower.com See their first chart "A". Your tower is most similar to the 72 foot, 31 sqft, @ 80 mph model. It depends a bit on the diameter of the tubes of
Does anybody out there have an EZNEC or other model of the TH-11? I am curious as to why the 20 meter director is the second element from the boom front end which makes the total 20 meter spacing 22
Has anyone out there successfully guyed a Universal aluminum tower? My current configuration is 30 taper, 26 st, 26 taper, 22 st, 22 taper, 18 st, 18 taper, and 14 top. It has a huge monstrous concre

I found the following review, by UU9JDR of Rig Experts, of how the different analyzers work to be very helpful. It explains the electronic design differences between most of the units out there curre
When a delta loop is designed for a particular band, and fed in the corner, it is not in an optimum configuration. They should be fed 1/4 wave length from the apex and then will act as a pair of phas
Because the band is so narrow, you can get excellent gain from a simple, two element beam on 30 using a short boom. For ultimate simplicity, a rotatable dipole about 6 feet above the Skyhawk will do
I have been using a shunt fed tower system on 160M since 1978. I first started out with a 60 feet Universal with a TH6 on top followed by 3 stacked mono-banders. The next iteration was growing the to
