GPS Antenna Cable
The standard SuomiNet GPS system comes with a 30 meter antenna cable. This cable will be modified to accomodate a lightning protector. Ideally, the lightning protector will be located immediately outside the receiver enclosure (typically a building). We need to know the cable length A, from the GPS receiver to the lightning protector, and cable length B, from the lightning protector to the GPS antenna (A + B = 30 meters).
For cable runs longer than 30m custom cables must be used. Obtaining these cables is the responsibility of the participant. The total cable loss can not exceed 12dB.
