I'm pretty certain the answer to that question depends upon more factors than you could possibly know or model, and if you can't model it anything else is a guess.

I am interested in knowing what the detriment might be if you had a 80 foot

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
