Make the right choice

Choosing a UHF antenna is easy - unlike mobile phones that have different frequencies, all UHF/CB radios transmit and receive on the one frequency - 477MHz.

Often the choice is more about practicality - for example, the choice of antenna will depend on the area where you're travelling.


Which UHF antenna is best for me?

A higher gain means a stronger signal, so when you increase an antenna's gain (i.e. its dBi), you reduce the angle it can receive signal - this means that high gain antennas are more suited to flatter areas, and moderate gain antennas (such as 5-6dBi) are better suited to hilly areas.


Which brand do I need - RFI or ZCG?

ZCG Scalar bullbar antennas have solid copper radiating elements, designed to last on even the toughest corrugated roads.

Typically, you will see RFI brand antennas on fleet and emergency vehicles in regional and rural areas because of their excellent performance for a very reasonable price - if you frequent unsealed roads or rough terrain, ZCG's UHF antenna series are the preferred choice.
