Remote Control Antennas

Choosing the correct remote control antenna and location are critical factors in determining how well your industrial remote control systems will perform. While there are many antennas on the market, Remote Control Technology can provide the options that work best with our wireless switch systems.

Antenna Installation

Successful wireless communication range is achieved for most industrial remote control systems when the following installation practices are observed. Remote Control Technology can supply connectors and RG-58 coaxial cable in lengths of 3, 10, 25, 50, and 100 feet (specify when ordering). Your range will be maximized by following these guidelines:

  • Mount the antennas at least 40 feet away from electric motors, large power transformers, power lines, VFDs or any equipment that produces ambient electrical noise. Otherwise, the receiver may have trouble distinguishing the FM transmitter signal from this noise.
  • When using 27 MHz systems, mount all antennas outdoors. This frequency has great characteristics for long range, but the signals will not go through metal-reinforced concrete walls. For equipment located indoors, run a length of RG-58 coaxial cable from the receiver to an antenna mounted outdoors.
  • When using 902-928 MHz systems, be sure that the antennas have a line-of-sight (a straight line could be drawn between the antennas without going through any solid objects). These systems are recomended for all indoor applications.
  • Mount antennas as high as possible, at least 3 feet away from vertical surfaces, and above awnings.
  • Use only high-quality cables and connectors, which are available from RCT.
  • Do not loop excess coaxial cable into a coil. This will cause a radio frequency choke and reduce your signal range. Loosely route it back and forth in an “S” configuration.
