Our 2" base station duplexers are ideal for compact high isolation installations. These filters are designed for the combination of two frequencies that require extra isolation, or they can be used as efficient preselectors. Selectivity can be determined by the field adjustable capacitors. Each cavity is temperature compensated for operation between -40ºC to +60 ºC. Each cavity has a gold Alodine finish, silver-plated loops, and silver-plated tuning rods. -

The F-33499 is a Covert Vehicle Antenna disguised in Shark Fin housing. This antenna provides 0 dBd of gain and less than 1.7:1 VSWR over 10 MHz bandwidth in the range of frequency of 406 to 470MHz. It has a radiation pattern nearly omnidirectional in azimuth. The shark fin style disguised antennas allow a public security organization to use a vehicle’s existing AM/FM antennas for both conventional radio receiver functions as well as allowing a two-way radio to communicate over the same antenna. This allows a covert vehicle to avoid the need for a long mobile antenna.
- 0 dBd of gain
- Less than 1.7:1 VSWR over its operating bandwidth
- A radiation pattern nearly omnidirectional in azimuth
- A broadcast coupler is optionally available
- Cross-band couplers when multi-band operation required on a single antenna
