Antenna Installation
Best Practices

We recommend the following practices to acheive a successful wireless communication range using the TRC Irrigation Remotes antennas in any location as long as the installation best practices are observed. Your range will be maximized by following these guidelines:

• Mount 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.
• Mount all antennas outdoors. Our remote controls (both FM transmitter and receiver) communicates in the RF radio frequency spectrum at 27 MHz. This frequency has great characteristics for long range but the signals will not go through walls. If your irrigation controller is located indoors; run a length of RG-58 coaxial cable from the receiver mounted indoors to the Part #01947 Cobra antenna.
• Mount antennas as high as possible; at least 3 feet away from vertical surfaces and out from under roof awnings.
• Use only high-quality antenna and cable connectors; which are available from our factory.
• Do not loop excess coax cable into a coil. This will cause RF radio frequency choke and reduce your signal range. If you cannot let it lie loose; wrap the antenna cable into a yarn-like skein of about 12 to 16 inches; or loosely route it back and forth in an "S" configuration.
