9.0 Preparing for Alignment
The Horizon Compact and antenna assembly is attached to the mounting post, or tower, with a
specialized mounting bracket that allows fine orientation adjustment of the Horizon/antenna assembly.
The same mounting bracket is used for all antenna sizes.
Visual alignment is achieved by rotating the assembly on the post, or tower, and positioning the assembly
so that the antenna is visually aligned with the target system before tightening the mounting bracket
clamp. Final alignment is achieved us ing the azimuth and elevation adjustment bolts. Once alignment is
achieved, the adjustment mechanisms are locked in place with lock nuts.
Figure 9-1 Mounting bracket with fine adjustment bolts
Final alignment is achieved by monitoring the received signal level (RSL) values as the system is
adjusted for azimuth and elevation. The BNC Field Strength Monitor connection is used in conjunction
with a voltmeter for RSL monitoring. See Section 9.1. Adjustments are made until the RSL value is at a
maximum, which should be within ± 3 dB of the expected value (link budget figure).
