ITEM NAME: RADAR SET
TYPE: AN/IPX-7A
INSTALLATION CONSIDERATIONS
TECHNICAL DESCRIPTION
Siting: The location of Radar Set
Frequency Range: 950 to 1150 mc in 12
AN/UPX-7A should be such that Antenna
channels
AS-133/APX can be mounted so that it
Center Frequencies:
will have approximately a line-of-sight
Channel 1 - 952 mc
path to the pre-flight test location,
Channel 2 - 969 mc
and high enough to furnish an open
Channel 3 - 986 mc
space for in-flight testing.
Channel 4 - 1003 mc
Mounting: If bench testing is to be
Channel 5 - 1020 mc
done, provision for spacing the antenna
Channel 6 - 1037 mc
of the AN/APX-6 at least ten feet from
Channel 7 - 1054 mc
that of the AN/UPX-7A should be made.
Channel 8 - 1071 mc
If only pre-flight or in-flight tests
Channel 9 - 1068 mc
are to be performed, it may I)e desirable
Channel 10 - 1100 mc
to install the set in a vehicle or
Channel 11 - 1122 mc
trailer.
Channel 12 - 1139 mc
