Hi, Lee If you accept that the aluminum elements of a typical Yagi have very little loss due to resistance, then perhaps you can accept the possibility that a 2-foot long piece of aluminum channel do
You didnt specify the wind loading of the DSTAR repeater antenna you intend to put atop this tower, but I have three comments: 1. Depending on the antenna wind load in combination with the zoning req
All the more reason they need to engage a Professional Engineer. Its possible they shouldnt even be _walking_ on the roof Bud, W2RU _______________________________________________ ___________________
Im not sure I understand what youre hoping to find. My 4-year old Rohn catalog makes it VERY clear that 30 feet of Rohn 25 can hold only 1.7 sq. ft. of added antenna when the environment is 90 mph (

Donna Please let me expand on Jims very important comment. I spent six+ years looking into antenna zoning restrictions in my search for a new QTH. In general and this may not be true in your locality
Whats wrong with these? Ive been using these for at least five years, and theyre fantastic: light-weight, minimal wind resistance, and UV-resistant. Mine are spaced every 18 on my open-wire lines. ht
Tim (& others) Be very careful when comparing a single 8-conductor rotator cable with two 4-conductor cables. Typically, 8-conductor rotator cable is special in that two of the conductors are heavier
