Antennas.us VL-1220-496 VHF Low Profile Airband Antenna
Antennas.us Model VL-1220-496 is a small, Low Profile VHF Aircraft Band Antenna. It covers the entire Civil Aviation Band of 118-136 MHz (General Aviation). The VL-1220-496 comes tuned from the factory so no adjustments are needed. This Airband Antenna is perfect for airport ground operations vehicles, where height restrictions exist: for example, traversing under aircraft wings. Measuring only 4" (10 cm) in diameter and 6" (15.3 cm) tall, this radiator is a very efficient Low Profile Antenna. Please note, the VL-1220-496 is not a ground plane antenna. Do not install on a fiberglass structure without adding some metal under the antenna to create a ground plane. Aluminum or another nonporus metal will suffice.
Your Antennas.US VL-1220-496 Purchase Includes:
- 1 VL-1220-496 VHF Low Profile Antenna
- 1 Mounting Bracket with 36' LMR400 Cable & Terminated End for ICOM A120 Mobile Radio
VL-1220-496 Installation Guidelines
While the VL-1220-496 is a low profile antenna, it will outperform a stick antenna when installed properly. For optimum operation, install it near the center of a flat metal surface, such as the roof of a truck's cab or van. Preferably, the immediate metal surface surrounding the antenna should have a minimum, approximately flat size of 50" (127 cm) x 50" (127 cm). Magnetic mounts or trunk bracket mounts are not recommended.
The VL-1220-496 Aircraft Band 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-1220-496 Airband 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.
