I apologize if this post is slightly off-topic for this group, but I'm
pretty sure you're the right crowd for the question...

I'm trying to connect a Yagi antenna to an old 915MHz WaveLAN wireless
access point (circa 1997). I have searched high and low, but cannot
figure out what type of connector I need. Since a picture is worth a
thousand words, I've taken the liberty of providing some visual aid!
Here is a picture of the mystery connector I'm hoping to identify:

Now, this looks suspiciously like an SMB connector. Alas, it is not.
I had a custom pigtail cable made (for $38!) using an SMB connector
and it is not a match. Here is a picture of the mystery connector and
the SMB connector side-by-side:

Close, but no go If anyone has an idea what this might be (or has
some other clever idea on how to get from the access point to a RP-TNC
connector) please, please let me know! And if you can cc: me via
email as well, that'd be swell - I don't want to miss your response.
