I have a WX worx receiver and combined comm/EM antenna. It looks like the WX

worx and the antenna use male SMA connectors. What coax should I use?

Thanks!

   What does the installation recommend? You can get sma connectors

   for about any of the popular coaxes. If your kit came with

   connectors, then you'd need to know which versions were supplied.

   Their is a high probability that any connectors supplied will

   be compatible with the common preference for RF-400 or RG-141 coax.

   However, it is possible that some other product fits your connectors.



   If no connectors are supplied, and no recommendations are cited

   in the manual, then RG-400 and compatible connectors would

   be my guess . . . although there are some new, lower loss

   coaxes that would work well at those frequencies.

Bob:

Thanks for the reply.  I apologize for my misspelling. It should have been

XM (not EM). It did not come with any connectors but I did find out it needs

to be 50 ohms. The supplied antenna has a permanently connected cable the

size of a single shielded wire. I'll try the RF400. Thanks.

   How long a run from receiver to antenna? RG-400 is noteworthy

   for it's stiffness. How important is it that the wire have

   some degree of flexibility? Is there receiver permanently

   mounted to the panel?



   Also, is the supplied antenna an "active" device? Many GPS

   antennas have pre-amplifiers built into their bases. You need

   to be sure that any proposed replacement antenna will perform

   as needed.
