I'm thinking about taking on the challenge of putting up a full wave loop for 160M and I'm curious what the minimum height should be. Is it worth the time and money to put one up if I can only get it 20-30 feet off the ground? I know I won't work much DX on 160 at that height, but it will be feed with ladder line, so I will be using it on other bands as well. Also, this loop would encircle my other antennas and I need to know how they will interact. How far away from the loop do they need to be? I'd like to be able to share supports to keep the cost down. Thanks.
