Antenna socket help

[scamper]

I just bought myself a new transmitter for this year (the one I bought last year died 3 days into the show)
I got the instructions to build a di pole antenna for it as I don't like the telescopic one that is supplied, but have hit a snag.
The socket on the back is half way between a BNC and a N type connector. And what's worse is it is a left hand thread.
Has anyone seen this type of connector before and if so, can you recommend where I may be able to get one?

This maybe?

Looks to tiny to be a normal UHF radio style connector PL259?

Yep too small for pl259.
Could be that one, I have a Jaycar not too far from me, So will go in there on Tuesday and see if it is the same, thanks for that.

Looks like a TNC socket. I didn't think that TNCs are left hand thread though.

yer its a TNC, i got sent out one the same when there ebay ad said bnc..
but i complained an got $10 off.. so that will pay for the adapter

Mouser part 523-122108RT is the TNC plug with reverse thread - crimp type to suit RG58 50 ohm coax

Looks good, except the $35 delivery charge ;-(
I may open it up and see if I can replace the skt at that price.
