[time-nuts] ThunderBolt question

[Robert DiRosario]

I have a Trimble ThunderBolt GPSDO that I just received. It has an F 
connector for the antenna input, and BNC connectors for the 1 pps and 10 
MHz outputs. Is the receiver input impedance really 75 Ohms, or is it 50 
Ohms and they just used the F connector to distinguish it from the 
others? What do people do, just use a 50 Ohm antenna?

Thanks
