Couplers

Couplers

Comprod is a leader in the design of RF filtering and coupling devices. The following are the specifications for couplers and tuners required as part of a disguised antenna solution.

  • Broadcast couplers – allow AM-FM broadcast receiver operation along with normal two-way mobile radio operation.
  • Crossband couplers – allow mobile radios on two different bands to operate with a single disguised antenna.
  • Antenna tuners – provide impedance matching and partly retuning the existing antenna to new frequencies.
