GPS repeater technical data
The L1 repeater unit has been retired, effective May 2019.
This kit includes an L1 / GLONASS / Galileo / Beidou repeater unit with a GPS L1 antenna.
The repeater unit has an effective coverage area of 40 – 50 metres radius from the centre, when mounted at a height of 10 metres.
The unit has a built-in antenna that radiates signal in a hemispherical-shaped pattern within a 180 degree angle of view.
Using the four moulded lugs, it can be mounted horizontally, for example on a ceiling, or vertically on a wall.
All that is required is good line-of-sight between the repeater unit and the receiving devices.
The external antenna feeder cable connects to an SMA socket; the repeater sends 5V DC through the coaxial cable to power the low noise amplifier (LNA) in the antenna.
If a larger area of coverage is required, additional repeaters can be added.

The antenna supplied with the L1 repeater kit is the Trimble Bullet.
The Bullet is an active antenna; it has an internal low-noise amplifier (LNA) that inserts 35dB signal gain.
The LNA boosts the received signal before it travels down the coaxial cable to the repeater input.
A 5V DC power source for the LNA is provided by the repeater through the coaxial cable.
The supplied universal mount and cable guide allows the antenna to be mounted on a vertical, horizontal or sloping surface.
See the repeater installation guide for full details.

The cable supplied with a repeater kit is RF240 low-loss coaxial, with an overall outer diameter of 6mm.
It is pre-cut and terminated with a TNC connector to attach to the antenna and an SMA connector to connect to the repeater.
It is offered in lengths of 10m, 20m and 30m, which means that most “standard” requirements are covered.
RF240 can extend to approximately 40m without any detrimental effect on signal strength or quality.
For longer distances the cable can be upgrade to RF400, which is similar in construction to RF240 with an overall outer diameter of 10mm.
