I have a Uniden 396XT that I use in my pick up truck to monitor a digital, trunked 800 mHz system. I have been using a cigarette lighter cord for power and an external antenna. I have a double, side by side Panavise Clip Caddy on my dash PanaVise Products, Inc. and it seems to work out just fine. I have pondered adding an external speaker, but the searches I have done here all seem to indicate that I would need an amplified speaker. Anyway, I am just wondering if anybody else here is getting by with a handheld on the dash and, if so, do you wish you had a regular mobile or are you fine with the handheld on the dash?
