Universal GPS parts and accessories

The following parts and accessories will work with most Brands / Models of receivers.

Radio Range Options

Land based radio communication range can be limited by a number of factors including, but not limited to:
– Terrain: hills and other land masses
– Obstructions: buildings and dense growth
– Interference: Radio and other Electro-Magnet sources including in-band, off-band and harmonic frequencies.

You have limited tools at your disposal to overcome these limiting factors:
– Raising the antennas at both ends
– Increasing transmitter power
– Finding a clear “channel” or frequency

We offer the following accessories to help you get the best range/performance from your GPS UHF Radios.

  1. Base Radio Antenna Extension cable. Raising the Base Radio antenna improves range and reliability at greater distance from the base.
  2. Long Range UHF Antenna. Designed and tuned specifically for use in the UHF band (450-470MHz). The 32” long Omni Directional whip is rated for 5dbi gain. Our test results showed a gain of: +15% in Range, +28% in area.
  3. Directional Base Radio Antenna. Focuses most of the Radio power in one direction. This can be helpful on long linear projects like Utility Surveys.
  4. Radio Interference Scanner. Detect radio interference and find a clear frequency without wasting valuable time.
  5. 1 Watt Radio Repeater kit. Extends your range up to 1.5 miles* by re-broadcasting the signal it receives from the base. *Range is still dependent upon terrain and conditions.
  6. 35 Watt External Radio kit. This kit can extend range between Base and Rover up to 20 miles depending upon terrain and conditions.
    FCC License is REQUIRED to operate this radio.
    6a. Satel Data-Power cable for Easy Pro 35 Watt Radio & BRx6 & BRx7 (not shown)
  7. Cellular communication. When local radio interference limits your performance, Carlson Listen-Listen service can help. This works by connecting the Base and Rover to the internet. AT&T SIM card data plan required for Base AND any internet connection method for the Rover (NOT included). Operation is limited by Cellular availability and RTK base line length limitations (approx. 50km). Perfect for use with RTK Drone.   Cellular fees, not included.
