Scanner Antenna for Portable Hand-Held Police Fire EMS & NASCAR. Hi-Performance, Long Range For UHF & VHF with BNC | RHWA-450-SBM

More InfoSpecifications Reviews

The RHWA-450-SBM is a high-quality UHF / VHF antenna for use in both the 150 MHz VHF band and the 450-470 Mhz UHF frequency range. This is a 10 inch tall, base loaded "half-wave" antenna and this construction allows it to receive transmissions at a far greater range than typical scanner antennas.  Our customers primarly use this antenna to monitor Public Safety (police - fire - ems) channels, as well as the auto racing bands like those used at NASCAR.  

The RHWA-450-SBM is made of all high-quality materials to the most stringent professional standards. The antenna is terminated with a stainless steel BNC type connector, which works with every UHF scanner and GMRS radio with a typical BNC connector, including: Radio Shack, Whistler, Uniden Bearcat, etc.  This is a very popular unit for the Uniden Bearcat BC125AT

See reviews for a write up on this scanner antenna for use with the Radio Shack Pro-668 & other UHF/VHF hand-held scanners.
