VHF Mobile in Vehicle Radio Antennas

A mobile VHF antenna often provides the coverage you need for your two-way radio while on the go. No matter what kind of car or truck you have, you'll find an antenna that installs to your vehicle, has efficient power requirements, and delivers optimal coverage. Choose a stand-alone antenna or select a kit that comes with all the cables, VHF and other accessories that you need to get the radio experience that you desire.

What's VHF within the context of radio and vehicle antennas?

VHF stands for Very High Frequency and has a range from 30 to 300 MHz. Bands are blocks of radio channels, and the two VHF bands are 6, which operates at 50 to 54 MHz, and 2, which operates at 144 to 148 MHz. Amateur radio enthusiasts, often called ham radio operators, use these bands and the radio channels within them to communicate. A mobile VHF antenna allows that communication to take place in a car, truck, or other vehicle, and there are marine VHF antennas for boats, too.

Do you need to drill a hole to mount these antennas?

No. A prevalent installation alternative is the lip mount. These devices support your antenna and attach to either your car roof or truck where the lid closes. Many antennas include this equipment, and this solution is quite secure but also convenient since no permanent changes are made to your car. Switch the installation between vehicles and upgrade your radio equipment easily when it suits you.

Isn't centered mount preferred over an offset orientation?

No. Although that was the case at one time. Since most car antennas were single band and repeater systems were inadequate, achieving the ideal ground plan made sense. Therefore, enthusiasts would drill a hole at the center of their roofs or trunks. Advancements in antenna technology have eliminated these challenges and minimized the benefit of a centered orientation in a ground plan.

Where should you mount a VHF antenna?

On a car or truck, the VHF antenna should extend above the roof line. Typically, installation on the driver side is preferred. Marine radio antennas can be installed almost anywhere, but if you have a cabin or other structure, then having it extend above that is ideal.

What should you do if you lack a metal surface?

Your car or other vehicle may be made from plastic or a composite material and thus not provide the VHF antenna with a ground plane. In that scenario, you need a VHF antenna thatu001as ground-independent. Many antennas are, but you should avoid any product with an electrical length of ¼ wave since such solutions depend on the ground plane to serve as the other half of the antenna.
