[TowerTalk] Balun for Quad

[Robie Elms]

Chuck,

I built a 1:1 current balun (choke) with one  2.4 " OD #31 core following
information published by K9YC. I used a PVC box approximately 4.5"
X4.5"X2.5" as a housing,  installed a SO239 a used ss hardware as terminals
for connections to the antenna.  It works well for my situation - wire
antennas and low power.  There are a number of suppliers with similar
commercial products.

I hope this stimulates some positive ideas!
