[TowerTalk] Fw: book Tribander comparison test

Let's say there was 5pF from each side of the choke to the boom - that's 
2.5pF net. At 30MHz that's a reactance of 2000 Ohms shunting the choke.

Not sure if that makes a difference in your application, but if I'd 
carefully designed a choke to have several thousand Ohms Resistive 
impedance I wouldn't want to be shunting it with 2K reactance.
