Covers GPS L1 & Galileo (1575.42MHz | GPS L2 (1227.60MHz) | GLONASS (1602MHz)
35dB gain active GPS L1/L2/GLONASS/Galileo antenna
This repeater unit has an effective coverage area of approximately 35 – 40 meters diameter when mounted at a height of 10 meters.
The unit has a built-in re-radiating antenna that radiates signal in a hemispherical-shaped pattern with a beam width of 180 degrees.
Using the four screw holes, two each side, it can be mounted horizontally, for example on a ceiling, or vertically on a wall.
It should be placed in a location where there is good line-of-sight between the repeater unit and the receiving devices.
The external antenna cable connects to a TNC socket.
The repeater sends 5V DC through the coaxial cable to power the low noise amplifier (LNA) in the outdoor 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.
For environments where moisture and/or dust ingress is an issue, this IP67 repeater is ideal.
However, it can also be installed in a dry environment, in which case the repeater is supplied with a standard (non-IP67) AC/DC power adapter.
If it is installed in a damp environment, a waterproof (IP67) power adapter is available.
The antenna supplied with the L1, L2, GLONASS, Galileo repeater kit is the Tallysman TW3872.
The TW3872 is an active antenna with 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.
