said by Fatal Vector:There really isn't that much use of the 30-50 Mhz "Low band" any more. Most of the state police agencies that used it are long gone to trunked, million dollar Motorola garbage.
Of course, when they finally auction off the analog TV VHF spectrum and move public safety to 700 Mhz, all those million dollar Motorola systems will be so much scrap and the equipment will hit the surplus market. I can see the hams licking their chops now. Mobiles and HT's for a song, trunking systems on the cheap....Hams will finally get to use some of the UHF and microwave spectrum they have.
This is a totally anecdotal statistic (no link provided, standard disclaimers apply 
), but I know there's at least one antenna manufacturer that is still pumping out about 2000 low band VHF base station/repeater antennas a year, so there's still a lot of use. Like most things technological, trends are cyclic. You'll see low band VHF become sexy once again after the higher bands get too congested or the county $100M high tech system fails.
