Harris P7300 Portable. Antenna Question

[tx2654]

P7300 Radios with OTTO speaker mics were issued recently to my agency.

It only came with one antenna. Should the antenna be taken off the radio and placed on the speaker mic and the radio's antenna connection be left without an antenna, or should a second antenna be used?

The manual does not specify, and I would like to avoid any radio damage. It APPEARS that the antenna, transmit/speaker audio/data is being rerouted to the speaker/mic, but wanted to ask in here.

Thanks

When a antenna capable mic is attached, all RF is routed to the mic's antenna. Each mic should have a threaded plug for the onboard antenna location.

I understand your predicament. Having the antenna mounted on the lapel mic usually makes it perform better however leaving the antenna port wide open for gunk, junk and sundry to enter the radio is asking for trbl. That radio represents a not to small an investment on your agencies part and asking users to leave it open to envirornment should be addressed.

To answer your question, when the lapel mic connector is pressed up to the case case it disconnects the radios antenna and routes the RF to the lapel mic.

Thanks for the replies. I was assuming this was the case, however wanted a few opinions on how it worked, for sure.

Harris supplies the radio with a threaded plug so the radio antenna connection is covered up with this plug to prevent any accumulation of debris.
