Feed Line Question

[blueclawsink]

Planning on purchasing an AirSpy HF+. I have antenna picked out but antenna has PL 259 connector. Anyone know where I can get 50 feet of feed line with the required SMA male connector to plug into the AirSpy HF+?

I would use RG 8x with 2 pl259 or 1 pl and 1 "N" connector. then use a jumper with a n or pl female to sma

Amazon has a listing for 50 feet of RG8X for $31.98 with PL259 connectors on each end. You could get that and then get a short 3 foot RG316 jumper for both stress relief on the HF+ and a conversion to sma male.

50 Feet RG8X
3 Foot SO239 to sma male jumper

If you don't quite need 3 feet on the jumper you could wind the excess around a ferrite core for HF noise reduction if needed.

I'd strongly recommend not try to connect RG-8 or LMR-400 directly to those type of small radios. It'll put a lot of stress on the SMA connectors.
Common industry practice is to use a smaller jumper to make the final connection between the heavier coax and the device.
A short jumper of RG-58 and the connectors will work just fine and will not have a noticeable amount of loss. It'll take the stress of the SMA connectors.

Custom made cables:

Get the SO-239/female UHF connector on one end to match your antenna, and put a female UHF or N connector on the other.
Then just get yourself a male UHF or male N to male SMA jumper made out of RG-58 or similar cable to make the transition.
