Roof Mounting Instructions
Preparing the Hole
Step 1.
Select an easily accessible mounting location on vehicle roof with no obstructions within a 24” radius. The
antenna should be as far away as possible (at least 18”) from other roof-mounted devices such as light
bars and other antennas to avoid de-tuning or interference issues.
Step 2.
Mark the location of the hole. Mask the mounting location with tape to reduce the likelihood of paint
damage.
Step 3.
Use a center punch to make a dimple on the marked hole location to reduce the likelihood of the drill bit
from walking. Drill a pilot hole with the 0.1” or similar diameter drill bit. Use a 1.5” diameter sheet metal hole
saw to drill the hole for the antenna. (Figure 1)

Step 4.
Clean up any metal shavings around the mounting location.
