Shoulder Mic with built-in Antenna

[mjthomas59]

Just purchased one of these to try out. Got it on ebay for a fraction of suggested price. My question is about why it has a bnc connector on it? There is 1 connector which you plug in on the side of the radio. Just above that is a large plastic piece with a bnc connector pointed downward, towards the antenna connector. There is about a 2-3 inch gap between the bnc connector and the antenna connector.

Can anyone tell me what this bnc connector is for? When I purchased the shoulder mic I assumed you would have an antenna on the radio and a 2nd antenna on the shoulder mic. The shoulder mic indicates it is designed for any of the HT1250/1550 and GP 360/380 radios. Is there another piece I have to buy to make this work?

Thanks for the help!

I believe you may be missing the antenna connector. It is an adapter that has a bnc to a "pin" type connector that goes down into the portables antenna connector. From experience, this external antenna setup is not very popular, nor is it recommended by anyone, because of inherent problems right away, or problems created by damage to the radio. Good Luck.

It sounds like you might have gotten a third-party microphone. I have an OEM for my MTS2000, and it does not have a separate connector for the antenna. There is a plastic button on the side that disconnects the antenna on the radio and routes the RF through to the antenna on the microphone. I find that it does help some when I'm in areas that are spotty in reception.

You will also find that these types of microphones have the straight cable rather than the coiled.
