Re: SMB Adaptor (again)

I've only seen them in the Collins R390/R390A and Collins aircraft radios. I don't know whether those are 50-ohm or 75-ohm.

Thanks,

They are pretty cute, but I've not seen 50 ohm versions. Do they exist?
And if they exist, do they mate with their 75 ohm cousins? (That may be
illegal in some states)

Tom,

Clearly my complete unfamiliarity with RF equipment of any kind betrays
me.

They're awfully cute little connectors. I'm a bit surprised that they
weren't
used more frequently on the various plug-in families: space is quite
limited
on those front panels.

My main exposure to RF connectors is the tiny, right angle coax connectors
used on modern laptops for the WiFi antennas. I expect that they are not
rated for a large number of connect/disconnect cycles.
