Many years ago I was working 160 meters and talked to a gentleman who gave me a specific length of 450 ohm ladder line for 160 meters. It was either 20'2" or 20'4". He told me not to deviate from that length. Well I'm older and have forgotten which length was correct and, I cant find where I wrote it down. Anyone have that information? I used a 160 meter loop for many years and this config worked very well for all bands with very little tuning necessary for all bands. I am now trying to get something up again but its not looking very good because of the lack of trees and a HOA that wont allow antennae.
