diameter by using the appropriate adapter (supplied).

Installation Instructions

Choose an antenna mounting location that is as high as feasible, 

as free as possible from obstructions, and as far as possible from 

other antennas and strong sources of RF.

1.  Loosen the wing nut on top of the Standoff Bracket and slide 

the retainer bar out of the way. Gently place the antenna in 

its mounting position in the U-shaped opening in the bracket. 

For 1

8

” and 1” antennas, put the appropriate reducing adapter 

(supplied) in the opening.

2.  Rotate the retainer bar over the antenna to lock it in place.
3.  Using the Standoff Bracket itself as a template, mark the 

position for its mounting holes.

4.  Drill ¼” mounting holes, and install the bracket using stainless 

steel machine screws, washers, lockwashers, and nuts (hardware 

sold separately). For mounting to some types of surfaces, you 

might need to substitute stainless steel woodscrews or other 

hardware (not supplied).

IMPORTANT:  If the thickness of the mounting 

surface is not adequate to support the antenna under 

expected stress, a wooden back-up pad (not supplied) 

should be applied underneath the mounting surface 

during installation.

5.  Tighten the wing nut to secure the antenna in the bracket. The 

completed installation should attach the antenna firmly to the 

mounting surface, leaving no “play” between the antenna and 

the standoff bracket.
