2.3.3 ANTENNA SELECTION

The KA 91 and KA 92 GPS active antennas, P/N 071-01545-0200 and 071-01553-0200 respec-
tively, are the designated antennas for the KLN 90B.

2.3.4 ANTENNA INSTALLATION CONSIDERATIONS

The antenna should be mounted on top of the fuselage near the cockpit. Avoid mounting the an-
tenna near any projections, the propeller, and the T-tail of the aircraft, where shadows could occur.
It is recommended that there be a separation of at least 3 ft. between the KLN 90B GPS antenna
and any VHF Comm antenna on the aircraft. Antenna baseplate must be level within 5 in both
axes when the aircraft is in level flight. If the antenna is tilted more than 5 or is mounted close to
other objects that shadow it, loss of some of the satellites will occur and system performance may
be degraded. Antenna cable and connector information, including vendor information, is listed be-
low. Refer to figure 2-10
for the 0 to 40 feet category using RG 400/U or RG 142B/U. Refer to
and BMA) for the 0 to 80 feet and 0 to 100 feet categories.

KA 91/92 nominal gain and noise figures are 26.5 dB
and 2.3 dB respectively. With 0.050 ice on radome,
gain will not decrease by more than 2.0 dB when
viewing a satellite from 30 above the horizon to ze-
nith, as compared to a no ice condition.
