VL-1500-496-CF, Low-Profile VHF Mobile Antenna, Custom Tuned

Low-Profile VHF Mobile Antenna, Custom Tuned

Model VL-1500-496-CF is a small VHF Antenna, Custom Tuned to your specified center frequency between 100 MHz and 300 MHz, designed for mobile platforms (vehicles) with height restrictions. Measuring only approximately 4" (10 cm) in diameter and 6" (15.3 cm) tall, this antenna is a very efficient Low Profile radiator. When installed properly on the metal chassis of a vehicle, the VL-1500-496-CF will perform comparably with a full size 1/4 wave monopole antenna. For optimum operation, install near the center of a flat surface, such as the roof of a truck's cab or van with minimum approximately flat dimensions of a half wavelength square. We do not recommend the use of a magnetic mount or a trunk bracket mount.

The VL-1500-496-CF VHF Antenna features a DC shunt connection to the chassis to help protect its attached radio from limited Electro-Static Discharge (you will measure a short circuit when measuring across its terminals with a multimeter).

An electrically conductive chassis/ground plane is required for the proper operation of the VL-1500-496-CF Antenna. If the intended mounting surface is non-conductive, such as a fiberglass roof, line the underside of the non-conducting surface with a thin foil of any convenient metal (Aluminum is widely used). Ensure that the NMO mount contacts the chassis/ground plane/foil securely.
