951/952 INSTALLATION MANUAL Revision B
The ACU connects to the 951X or 952X with RG-58U coaxial cable, which
carries signals to the differential receiver and DC power to the ACU
amplifier. See Figure 17 below for the correct AN150/8410 wiring. A
25-foot length of this cable is supplied with the unit. This cable may be
extended up to a length of 300 feet. The cable passes up through the hol-
low ACU base and connects to the PL-259 (UHF) connector at the bottom
of the ACU. For UHF connector preparation, see“Differential GPS antenna
cable connectors” beginning on page 25.

CAUTION!
Maintaining the ACU’s weathertight seal between its upper and
lower halves requires only hand-tightening the two together.
Using a wrench or other tool may distort the gasket or housing/
rubber O-ring inside, or break the coupler base.
NOTE:
This connection must be made before the ACU is screwed into
its base.
