Besides common-mode pickup, *also* consider whether your Beverage antenna
is pointing at a source of noise.

Carol – Regarding the use of ferrite chokes to kill common-mode noise coming in
on the transmission line, look on the internet for “A Ham's Guide to RFI,
Ferrites, Baluns, and Audio Interfacing,” by Jim Brown, K9YC. It’s a very good
tutorial on how to construct and use chokes for common-mode n
Hi Carol
The big issue with any RX antenna is common mode noise, the feed line can
interact with all other wires in your station, including AC wires 115Vac,
rotor cables etc.
Try this, on 9:1 transformer, remove the beverage wire and connect a 450
resistor. Removing the wire for the resistor de
What value termination resistor, how far did you drive the ground rods, did you
slope the last 50' on each end?

Hello all,
I finally put up a beverage antenna...about 400 feet long. I am feeding
it through a 9:1 transformer with some 50 ohm cable ( RG 59). I am
finding that it is noisier than my transmit antenna, contrary to what it
should be. The wire stays about 6-8feet above ground. ground rods at
