Garmin Transponder RF Adapter

I'm looking for an Garmin RF adapter #330-00326-00 for a GTX320/320A transponder if anyone has one or knows where to get one.

Do a search of the part number and you will find several of them from avionics suppliers, albeit pricey in the $30 range.

However, it's not a particularly odd part. It is just a blindmate to BNC adapter. Available from Digikey, Mouser, Jameco and a host of other electronics suppliers for abour $1.50

Or you can use a RG400 to blindmate connector.
