Comant CI511 GPS Attenuator

When used with 26.5 dB gain ComDat GPS antennas, the CI 511 GPS Attenuator allows operation of Garmin GPS systems that require 17 dB gain. The CI 511 reduces RF gain by 12 dB. Built-in bias bypass circuit allows full supply voltage, provided by the GPS receiver, to pass directly to the active GPS antenna without DC voltage drops. Current supply is not reduced. Should the Garmin GPS system later be upgraded to WAAS and 26.5 dB gain, simply remove the CI 511 from the coax. The antenna will not have to be removed and
replaced.
