I am a retired USN, flight deck guy and have had plenty of experience with military spec handhelds and base-stations. I now have the honor of working at a homeless shelter/ campus. We are looking at a commercial license, have a 3rd party on the hook to help us get an FCC license, and I have purchased a scanner to explore frequencies before I submit for that license. We need cheap radios our guys and gals can use for dependable communication. I also live, down a river channel from the Mission, two miles away and would likely mount something at home so as to monitor Campus communications as well. We have 8 buildings made of sandstone and/ or metal warehouses (and some cinder block walls around offices) scattered across roughly 25 acres of land in the Norfolk, Virginia city limits. We have been using FRS/ GMRS radios in the FRS range, but now have realized and repented of our wayward ways and that we are not using our radios appropriately (legally) and are going to need find another means of legitimate communication. These FRS/ GMRS radios weren't working that great to begin with since I could not mount antennas externally, and the building walls are fairly thick. VHF/ MURS is possible, but UHF really sounds more appropriate for us and would likely be our best bet anyway. With the 500 ERP limit in mind, In another discussion (MURS) I was steered toward inexpensive Motorola VHF Maxtrac for base units, but I see that there are many in the UHF range as well -any other favorites thoughts about antennas, radios/ handhelds?
