RG-59 cable is fine but soldering wires is not a good idea for 1.6GHz.
Use a panel-mount BNC crimp connector made for RG-59 such as the
Amphenol 31-343-RFX. I presume you want to use regular 50 ohm BNC types
rather than the 75 ohm variant.
It is preferred to use coax for the 1 PPS as any reflections will
degrade its risetime.
Good luck,

Hello,
I am looking for the advise: what will be the better method to connect
GPSDO module by short extension cable to put its antenna input on
front or back panel ?
Lets say, GPSDO module has female âFâ connector. And I would like to
have BNC connector on back panel of my project. Manufacturer of GPSDO
recommend to use RG-59 cable for antenna connection.
Is it OK if I'll take some RG-59 from CCTV, cut 6" or 12" of it,
connect one end to GPSDO (let say this cable has compression type
connector) and solder other end to BNC on the panel ? Or its better to
use adapters and no soldering ? Like "F connector-to-BNC" adapter ,
then short BNC-to-BNC cable connected to BNC panel connector ?
And other question: is it worth to use RF cable to connect 1PPS output
from GPSDO to distribution amplifier ? Or regular AWG-22 could do that
job ? Thanks !
