Bulletin 237391

Revision 'D'

Vertical Antenna Mountfor 2.4m (8ft) and 3m (10ft) Parabolic Antennas

Installation Instructions

DescriptionInstructions given in this bulletin apply to the mount assemblyfor shielded and unshielded antennas with diameters of 2.4 m(8ft) and 3 m (10ft). The mount attaches to the reflector at 3 pointsand is offset from the center of the reflector to accomodate thefeed. The mount may be offset from either side of the feed centerby 200mm (8”) and attaches to the antenna mounting pipe of thetower with 4 U-bolts. Inverting the mount position on the reflectorprovides the alternate offset from the feed center.

The U-bolts can be loosened for coarse azimuth adjustment. Afine azimuth strut assembly is included for adjustment of azi-muth from -5° to +5°. The mount also includes an elevationassembly for adjustment of elevation from -5° to +5°.

Shielded antennas require a fixed strut and strut bracket at therim of the reflector for greater stability. This strut is located on theopposite side of antenna center from the azimuth adjustmentstrut.

Notice
