I'm trying to ask a question on this forum. How far does a antenna have to be from a wall? I live in a tower block on the 5th floor. Wanna bolt a silver rod to the to the front of it from through the window? Please help. I live in Tottenham London. Got a cobra 148 gtl dx with a tear drop power Mike. Silver eagle too

Hello Keats,

Generally all antennas should be sited in free space away from any objects. However sometimes that just isn't possible. If you are mounting it on a wall with the radiating element above the rest of the block you're in with a chance but if you want to run the entire antenna up against the wall that's far from ideal and I suspect you will run into problems tuning it. If possible try and stand it away from the wall as much as practicable.

I guess the best thing to do is give it a go and see what results you achieve.

73's Gary.

With a tower block unless it's above the roof as far as you can get because it'll capacitively couple to the rebar in the walls of the tower making it a real sod to tune.
