It is a common RJ45.
You can get them almost anywhere.

I'm looking for the mic plugs that used to come with the GR300 repeater
packages. The plug that goes in place of the mic in the front of the radio
to close the ground.
I only need a few, so if you have a couple and are looking to get rid of
them email me directly.

thnx
