Vehicle-mounted UHF antennas are commonly used for two-way radio communication in Australia, as they are a crucial tool for maintaining connectivity, especially in remote and rural areas without 4G connectivity. Typically operating in the 476-477 MHz band designated for the Citizen Band Radio Service, these antennas are often mounted on the bullbar of a vehicle using a sturdy spring base. This spring base not only facilitates easy installation but also adds a degree of flexibility, allowing the antenna to flex and bend when encountering low-hanging obstacles, reducing the risk of damage.
There are several types of these antennas, such as the ground-independent collinear antenna and the elevated-feed antenna, each providing different levels of gain suitable for varying terrains and ranges. These antennas, combined with a quality UHF radio, ensure reliable communication for both commercial and recreational users, making them an indispensable asset for anyone travelling in the vast Australian landscape.
