Product Details

The original patented Phantom Field Diversity low profile antenna sets industry standard that can not be duplicated.

The Antenex Original Phantom low profile antenna requires a standard NMO mount. Most NMO mounts are installed by drilling a hole in the roof of your vehicle (roof must be metal). The cable is then routed under the headliner to the cellphone's location. This provides for an excellent ground plane and very solid permanent installation. Trunk lip mounts are also available.

Note: This antenna features a tunable frequency range of 142-160MHz with a 1MHz bandwidth. What this means is that the antenna can be tuned to any 1MHz band within the range of 142-160MHz.
