Wade probably has some critical resonant length of feedline that feeds
RF back to this station from the antennas when his good earth bonds are
In this case, he has done a good job of earthing his station. The only
improvement any ham can make is to always use copper ribbon in place of
round wires, to have lower inductance in that ground lead.
Usually, a feedline should not be a quarter wave odd multiple in length
at any band you use. Use of a balanced antenna tuner with open wire
feeders is best, but you can use a high quality line choke or 1:1 balun
in many cases, and 4:1 in other cases. Sometimes, you have to try it
out to find the best balun set up.
