[TowerTalk] Shunt fed tower for 160m

[Stan Stockton]

I am interested in knowing what the detriment might be if you had a 80 foot tower with a large Yagi for top loading within four feet of a 20 foot tall concrete building with lots of rebar and a metal roof.  

I’m not worried about matching the tower for 50 ohm feed but worried about whether the concrete structure will attenuate the radiated signal and if so, by how much.

Thanks…Stan, ZF9CW
