The F-33496 is a Covert Vehicle Antenna disguised in Shark Fin housing. 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. A broadcast coupler is optionally available, to allow the two- way radio transmit and receive frequencies to be shared with the vehicle’s AM/FM radio. The coupler prevents the transmit radio from damaging the AM/FM radio.
- 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
