TESSCO is your source for all the non-Trimble components you need to build, operate, maintain and use the RTK Network system.

Trimble Approved RTK Network Components

Power Source RF Cable Antenna Mounting Structure

Power Source for Trimble RTK Network

A shared base station requires about 1- 3 Amps or 12 Watts of power continuously. Although the power requirement is small, it needs to be continuous, regulated, and consistent to provide good correction signal to the RTK vehicles. Any power surges or losses could disrupt the signal and cause line jumps or loss of signal.

Trimble recommends all shared base stations receive their power though a 12VDC battery system. There are two main powering solutions depending on the power availability at the shared base station site.

LinkUPS for Trimble RTK Networks

LinkUPS™ Backup Power Systems for RTK Networks

The new VENTEV LinkUPS™ outdoor backup power system is specifically designed to provide both primary and uninterrupted, reliable standby power for critical RTK equipment in harsh environmental applications.

RF Cable (Low Loss Coaxial)

This cable transfers the radio signal from the RTK Radio to the Antenna. Coaxial cable does lose signal power the greater the distance it is transferred. Make sure you compensate for this loss with a higher gain antenna and high quality low loss coax cable. When constructing your shared base station, the radio and antenna can be mounted at the top of the tower requiring a small coaxial cable or at the bottom of the tower requiring a longer coaxial cable. Remember, the longer the coaxial cable, the bigger it must be to compensate for the signal loss. The size of the antenna does not matter if the signal cannot get there.

Antennas

The antenna broadcasts the sub-inch correction signal to all of the vehicles within a 12 mile line of sight radius. Omni-directional antennas are recommended because they put out equal signal in all directions. No matter how you set your RTK Network up, the antenna should be mounted as high as possible to broadcast the correction signal to the vehicles below. All other components, including the RTK radio can be mounted near the ground.

Mounting Structure

All of these components are mounted on or near some type of structure. These structures could be radio/cell towers, water towers, grain elevators, buildings, or other tall structures. Due to their height, all of these options will need to be grounded and have lightning protection to protect the electronic equipment.

Note: If you mount the receiver on the structure itself, make sure it does not move or sway.
