This antenna is designed to be mounted through a 3/4" hole drilled through the body of a vehicle.
Considered by many to be one of the best performing CB antennas ever made, you absolutely cannot go wrong with the Wilson 1000. We've promoted this antenna for years based solely on how well it works, it also boasts durability and longevity.
It's not uncommon to see this antenna last for over 5 years or more, it's simply built that well. One of the many things Wilson did correctly while engineering their (magnetic/roof/trunk) mount line of antennas is to give the 1000 and 5000 models the ability to remove the load (the part that says Wilson on it) on up, while keeping the base and coax secured to the vehicle.
