GENERAL
1.01 The KS-15970 parabolic antenna (Fig. 1) is
a dually polarized, 5-foot diameter, parabolic-
reflector antenna.
It consists principally of a
spun-aluminum dish and a simple primary feed
system. The feed system is protected by a
'laminated-glass-fabric dished radome, which is
attached to the frent of the reflector flange. The
antenna is arranged to mount with standoff brackets
and a T-frame.
The brackets and frame permit
independent azimuth and elevation orientation
adjustments when the antenna is used as a direct
radiator, or in a periscopic system.
1.02
The KS-15970 antenna is intended for use
in the TJ and TL Microwave Radio Relay
Systems to transmit and receive microwave signals
in the frequency range 10.7 to 11.7 GHz.
1.03
The antenna is covered by the following
specification and list numbers:
