Antenna Installation Guide 

Pull the antenna whip so that the bushing seats into the rubber insulator of the base-cap: 

 

Thread the base-cap onto the antenna base, using a rubber washer only if the mounting surface is 
less than 1.25 mm thick, then 

tighten another one-eighth to one-quarter of a turn

.  

Note:  If the 

antenna whip feels loose to the touch, remove the rubber washer and/or adjust the bushing so that 
the bottom end of the antenna whip protrudes further from the bushing.
