These units are nice, work great,speaker is big enough puts out big sound, unit is compact, over all neat design. I use mine with a Uniden 29LTD aclassic, which is a little , bigger, then some mobiles. There are eight screws, you take out to get top cover off, you have to go inside to hook up the power supply, speaker, and coax, Simple just takes a few minutes, and you are ready to modulate.Built in SWR Meter. The color scheme will go with about any location.This beats having to use an off size power supply, with your mobile radio setting around it, or off to the side.Using the MBPS keeps everything, neatly together. Hope to hear you on the air. The Double Duce of NC.
