GPS repeater kit for L1 signals
GPS repeater kit for L1 signals (1575.42 MHz)
A GPS repeater brings the outdoor signal inside your building; it is usually supplied as part of a kit that comes with all you need for a successful installation.
Each kit contains:
- 35dB gain GPS L1 receiving antenna
- Flexible antenna mount system
- Coaxial cable; 10M, 20M or 30M
- Variable-gain repeater unit
- AC/DC power adapter
GPS L1 repeater
The L1 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 cone-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 – all using a single outdoor antenna – by use of a GPS signal splitter and/or a line amplifier.

Installation of a GPS repeater kit is straightforward; a guide is provided with each kit.
FalTech is happy to advise on specific installation issues; below is a quick overview of the process involved.
- To ensure that the GPS repeater receives the best possible signal, the outdoor antenna should ideally be placed on a roof where it has an uninterrupted 360° view of the sky.
- Keep the antenna away from other equipment that may be present on the roof, such as mobile telephony masts, microwave transmitters and air-conditioning units.
- If it is not practical to install the antenna on the roof, it can be mounted on south-facing wall, using appropriate bracket.
- Install the coaxial cable from the antenna to the indoor GPS repeater unit.
- Place the GPS repeater unit indoors, on any vertical or horizontal surface, where clear line-of-sight is available to any device(s) that need to receive GPS satellite signals.
- Connect the power to the repeater unit via the supplied AC/DC adapter.
- Adjust the gain control to the optimum setting by observing the multi-coloured status LED on the repeater.
