Enhance Range Of Linear Receivers

The Linear Omni-directional Remote Antenna (EXA-1000) is designed to enhance the radio range of Linear’s receivers. This antenna can be connected to the F connector on many Linear receivers to improve their range when they must be located in poor signal reception locations. Usually an increase of 20-30% range can be expected. The versatile EXA-1000 can be mounted in a variety of ways. A 2-inch U-bolt is supplied for post or pipe mounting, or the U-bolt holes in the Base Plate can be used to screw the antenna to a wall or vertical wood brace or beam.

  • Omni-directional remote antenna
  • Includes 5 feet of coax
  • U-bolt for post mounting

Note: Generally, the higher the antenna is mounted above ground level, the better the radio range will be.

The EXA-1000 is a 1/2 wave, center fed, vertical antenna composed of three parts: an Antenna assembly with an F connector attachment; a Base Plate assembly with radial mounting provisions; and a five-foot, 75-ohm coaxial cable. The cable connects to the antenna base on one end and the receivers F connector on the other. If the antenna must be mounted further than five feet from the receiver, an extension cable of up to a maximum of 25 feet may be used instead of the five foot cable supplied. Because of the cable resistance, the performance of the EXA-1000 may be degraded by using longer than a 25 foot cable.
