F-3990 This VHF antenna is designed for applications that require peak performance in the 136-174 MHz while tolerating a VSWR around 2.0:1. This antenna has a loading coil between the radiating element and the base. This coil increases the electrical length and makes the antenna perform electrically as a 1/4 wave antenna, but shorter than a regular 1/4 wave antenna. Typical gain, when mounted on a ground plane, is comparable to a full 1/4 wave. Mounts on NMO. The upper element is made from a brass wound cable with a flexible shaft core, well sealed using rubber shrink material. This solution offers a high reliability and prevents breakage or brittleness. Other frequencies are available upon request. DOWNLOAD PDF -
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

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.
