RF-Baton! Transmitter Controller Installation and Operation Preinstallation
June 1999 6880497G01-B 3-5
The maximum allowable cable loss between the GPS antenna and the RF-B! transmitter
controller is 6 dB. The maximum cable loss includes additional considerations, such as
line-of-sight loss and minimum satellite power during satellite acquisition. The total
line-of-sight loss (7 dB) includes foliage loss (for example, low density tree tops, 6 dB) and ice
loss (1 dB).
Only one GPS receiver may power the GPS antenna; all other ports to other receivers must be
DC-blocked to prevent damage.
Antenna Requirements
Use antenna lines with silver-plated connectors (male and female) to reduce interference
(intermodulation) problems. For example, mate a male connector with a silver-plated center
pin to a female connector with a silver-plated outer conductor.
Mark all antenna feed lines appropriately to ensure connections to the proper locations. Use
colored, vinyl marking tape designed for outdoor purposes to mark the antenna feed lines.
Terminate all antenna feed lines with a suitable surge arrestor within 12 in. (30.48 cm) inside
the entry window. Connect each arrestor to the master ground bar located below the entry
plate.
