All About VHF Radio Antenna Products
VHF radio antennas are built with transmission hardware for base unit circuits or mobile hardware. The handheld technology that powers an external antenna can receive and transmit signals at both close and long range. You'll find portable antenna options that can be used with products by Baofeng, Icom, Kenwood, and Yaesu.What are the band options for portable VHF antennas?
- Multi-band: These portable products are engineered with hardware that can operate in various frequencies. This means that there are circuits that help the hardware distribute a signal while other circuits run on a different frequency. The big benefit is that portable multi-frequency accessories give users opportunities to pinpoint the most efficient signal while in areas that have spots where interference could occur.
- Single-band: Single-frequency accessories can only pinpoint a radio signal using one frequency. However, by using multiple single-band products, you can operate different ham radios on different frequency bands. These antennas are commonly used on police radios and scanners.
- Dual-band: Dual-frequency products can detect signals that are on two individual bands. These products can be used two ways while operating a ham radio. During tactical situations, you can operate a ham radio using each frequency individually. You could also configure a radio so that the hardware will use both frequencies. To take advantage of these options, you'll have to equip a dual-frequency antenna.
Diamond portable antenna accessories have a gain of 4.5/7.2 dB. On average, these handheld antennas can generate a maximum power of 200 watts. In harsh environments, a typical Diamond antenna can hold a signal thanks to the a dense material it is made from. It has a 135 mph wind rating.
Nagoya portable external antennas are nearly 16 inches, so they can be used in many outdoor areas that are surrounded by trees. These portable products have a flexible housing that's dense, and the hardware underneath this housing is specifically designed to boost a signal.How do you install a portable antenna?
Each portable antenna will have a different installation procedure. Specific instructions can be found in the owner's manual. Most antenna systems are designed with a mechanism to mount it in place. During the mounting process, no screws or other hardware are needed, as the mechanism has grooves that lock the hardware onto the radio housing. After a portable antenna is secured, it can be adjusted so that the hardware can detect the strongest signal in an environment.
