I am still working on my new Beverage antenna. I have run about 400 ft of F6-type flooded coax from my shack to one end of my Beverage antenna. My question is: do I need to install a feedline current

Wayne, What is more important than a little weak noise is common-mode signal. Why don't you also test to see how well you can hear any AM broadcast stations with the coax terminated? Please also tell
