Greetings friends... I reside in Ocala. I mainly monitor Marion Sheriff, Fire Rescue and Ocala PD and Fire Rescue... I also enjoy monitoring the new Lake County digital trunked system which incorporates some frequencies in the 700 mhz band. I use a vehicle antenna and its made by Motorola. here is a link to an ebay item. I purchased this exact model number a while back and it works flawlessly. If you require an antenna on a vehicle for scanning purposes, and you monitor Marion, Ocala, and Lake Counties, this antenna will receive all 3 trunked systems with no problems, as long as your monitoring with-in this listening area. I know its hard to find a tuned antenna that incorporates the newer 700 mhz frequencies, so I thought that I would share this with you. I am not afiliated with this seller, just passing on info. But I have purchased from him in the past on more than one occassion, and they were all good experiences.
This Motorola NMO mount vehicle antenna is set for 764 to 870 mhz
Lake County operates on 769 to 853 mhz
Marion County operates on 851 to 853 mhz
City of Ocala operates on 852 to 860 mhz
Keep in mind that this NMO mount antenna requires you to drill a hole thru the metal to mount the antenna mounting base and coax wire... it will also need to be terminated with the propper connection to mate up with your scanner. I installed a BNC connector on the end of my coax, in order to connect the coax to my scanner device. NMO mounts are typically seen on the roof or trunk of a patrol car, or the roof of a fire truck or commercial use vehicle which utilizes 2 way radio communications equipt.
