Antenna Mounting 

 

CompuStar antennas can, in general, be mounted with any orientation. Horizontal or 
vertical, doesn’t really matter. Things to consider would be the routing of the antenna 
cable, and mounting the antenna a few inches down from the roof and/or tint line. If the 
antenna cable is pinched or crimped on its way to the antenna, the system may experience 
problems such as; poor range, one-way communication on two-way models, or possibly 
no response at all. Metal acts as a natural shield to radio frequency signals so mounting 
the antenna close to the roof, or behind some kinds of tint that have metal content to 
them, can cause poor performance.
