Topband: CONNECTORS AND CABLE

Cheap RG6, the one with CCS center conductor, sometimes shows quiet high
losses (few db per 300ft.) at 1-5 mhz and at the same time quiet low at
higher frequencies;

Not only the losses but signal leakage is important and not every brand of
RG213 or RG6 is suitable at some instalations;

YMMV
