Topband: Broadband Inverted L

[Joe Galicic]

Tom there are many other things in the mix here. Five houses within 30-40 feet, Hi-Z receive antenna within 10 feet of transmit antennas, three other wire antennas sharing the same trees and air space. And yes the old L is still there at about 60 feet away. I don’t think I'm the only person in this situation however. I will either detune or take down the old L. Thanks for your patience! -Joe

Hi Joe, 

Do I understand this correctly? You have both inverted L's up only 40 feet 
apart, with one of them running directly over a tree?? 

Unless you are detuning unused antenna, anything you observe is an unknown 
mix of things. Are you detuning the unused antenna? 

How many other things are in the mix? 

If it is just one Inverted L, then how are you comparing levels between 
them? You can't compare levels with only one antenna up at a time. 

I don't think it is possible to reach conclusions or offer advice about 
systems before understanding the entire layout.
