Step 4.
After selecting the location to mount the Antenna, mask the mounting location to avoid paint damage. Then mark the
hole center with ink or scribed cross hairs.
Use a center punch to make a dimple on the marked location to avoid drill bits from walking across the sheet metal.
Then use a Twist drill of diameter about 0.1” and drill a pilot hole. Then using a 1.5” diameter sheet metal hole saw, drill
the hole.
The hole saw will cut the required diameter hole with less risk of stretching and distorting the vehicle surface. Clean up
any metal shavings from the hole cutting process. (Figure 3)
