In some cases a small patch antenna may be used. Typically this kind of solution is used
in research labs where the receiveantenna can be easily located outside by the window.
The indoor coverage is typically greatly reduced in this case and feedback may pres-
ent a problem (indicated by RED led indication), but is typically sufficient to bench test
handheld GPS equipment.
Hint:
the location of the outside antenna can be easily located by using a GPS receiver
to read the coordinates through the repeater.
3. Power supply
The GPS Repeater system is powered by a DC wall adapter supplied in the installation
kit.
4. Cable
The standard cable supplied with the repeater is of RG58 type, which can be used for
cable runs of up to 20 meters. Cable runs up to 40 meters can be realized with RG214.
Longer cable runs may require a separate line amplifier to compensate the power loss in
the cable .
ROGER GPS Repeater, transmitter unit
The transmitter unit is the main component of the system. The GPS Repeater
transmitter contains filtering, amplifiers and power control circuits. The GPS Repeater
also supplies power (+5VDC, max 100mA) to the outdoor antenna through the antenna
cable.
