It's NOT a good idea to splice in to the antenna lead for a hand held. If you transmit on the handheld and the panel mount unit is in RX mode, damage can result. You would be better off with a method to disconnect the internal radio before conecting the handheld to the antenna. Connecting for power is not a problem.

Subject: handheld radio panel plugin


hi all,

anyone have experience with a plugin(switch) for a handheld radio to go through the external antenna ie for a backup to a radio failure.  in the spirit of redudancy, i was thinking of adding this to my panel as early on i had a stuck mike(fixed with replacement of the audio panel) and i thought this may be a worthwhile backup.  however, upon looking further into this, apparently it may rob the panel mounted radios of db's and i have read that when it is used it may damage the panel mounted radios. fact or fiction?  is it worthwhile? downsides?

thanks,
