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.

- Frequency range of 138-174 MHz
- Unity gain achieved over its operating bandwidth
- Used for vehicles, such as ambulances, where vertical clearance is critical
- This antenna is ideal for a vehicle that enters areas with reduced headroom
- Combined with a matching circuit that is mounted inside the vehicle
- Each antenna assembly is individually calibrated on the roof of a vehicle
