I want to run 2 sdr dongles off a single antenna (mobile installation). I can't find the splitter I want: sma x2 to SO239, so I was going to build my own. In my head I was going to run the thin coax from both dongles together in heatshrink or braid, but wondered if they would interfere with each other so close.

I'm very new to radios. Shameless thread plug coming... I posted this in the SDR forum looking for help on my entire desired system:

If anyone wants to give me any pointers with assembling my sma/SO239 adaptor or looking at my other loooooong thread I would greatly appreciate it.
