Re: [Towertalk] Choke Balun on RG-59 Coax?

[Joe Reisert <jreisert@jlc.net>]

Eric,

Assuming you are using the correct type and amount of ferrite beads, the 
coax type will not change the attenuation one bit. 50 type 73 beads should 
do OK on 80 and so so through 160 meters. However, I use 100 so that the 
160 meters for a greater margin and more de-coupling. These receiving 
antennas are very sensitive to feedline coupling which really can degrade 
the inherent performance.

73,

Joe, W1JR
