Topband: Mother of all ferrite common-mode coaxial chokes

[Bob K6UJ]

I agree with Tom on the F-connectors.
I (now) have great results with the type-F connectors for my low band receive antennas.
I was getting flaky connections with the connectors for some time and finally got a decent 
installation tool.  Got a good F connector compression tool, for $55.00 (ouch)  but now no problems.
I watched a DirecTV guy one day using his compression tool and realized that is what I should use !
