  • Description

The CA-2x4SR is a broad-band antenna designed for those needing voice communications on the ham radio, public service, land mobile, GMRS and FRS frequency ranges.


When the amateur radio community is working together with local search and rescue and other public service agencies, the CA-2x4SR antenna allows TX and RX capability in both bands!


The coverage area and gain provided by the CA-2x4SR is remarkable. Whether used on VHF or UHF or both, it is an asset to the communications needs of amateurs and land mobile users simultaneously.

CA-2X4SRNMO Features

  • Broadband VHF/UHF Coverage (140-160 MHz & 435-465 MHz)Operate across 2 meter, 70 centimeter, GMRS, public service, and commercial frequencies without constantly swapping antennas. Great for users who need flexibility between ham, business, or emergency communications
  • High Gain Performance (3.8 dBi VHF / 6.2 dBi UHF)Helps improve transmit and receive range compared to many compact dual-band antennas, especially when working distant repeaters or rural coverage areas.
  • Wideband Low SWR DesignEngineered for broad frequency coverage with low SWR across both bands, reducing the need for constant retuning and making the antenna useful for multi-service applications.
  • Fold-Over Hinge IncludedEasily tilt the antenna down for garages, parking ramps, low branches, or storage without removing the antenna from the mount.
  • Built for Search & Rescue and Public Service UseDesigned specifically for operators who may need to communicate across amateur and commercial/public safety systems using a single antenna setup.
