Frequently asked questions What is the difference between 27MHz and 477MHz for CB radio?27MHz is the frequency band used by traditional AM and SSB Citizens Band CB radio, which was the dominant vehicle communication standard in Australia for many decades. 477MHz is the current Australian UHF CB standard operating across 80 channels, offering clearer audio and better performance in most environments. The AB001 suits antenna types for both systems. What is 5/16" TPI and what antennas use this thread?5/16" TPI refers to the thread diameter and pitch of the antenna base connection point. It is one of the most common antenna thread standards in the Australian CB and UHF CB market and is used by GME and many other antenna brands. Confirm that your chosen antenna has a male 5/16" TPI base thread before purchasing. What mounting style does the AB001 use?The mounting style of the AB001 is not confirmed in the available source data. Common antenna base mounting types include magnetic, gutter mount, body hole mount, and stud mount. Contact us to confirm the mounting method before purchasing. Is a coaxial cable included with the AB001?Cable inclusions are not confirmed in the available source data. Contact us before purchasing to confirm whether a coaxial cable is supplied or must be sourced separately. Is the AB001 compatible with antennas from other brands?The AB001 uses a standard 5/16" TPI thread which is common across many Australian CB and UHF CB antenna brands. Antennas from other brands using the same 5/16" TPI thread specification may be compatible. Confirm thread specification with your antenna manufacturer before purchasing. Frequently Asked Questions What is the difference between 27 MHz and 477 MHz for CB radio? 27 MHz is the frequency band used by traditional AM/SSB Citizens Band (CB) radio, which was the dominant vehicle-to-vehicle and recreational communication standard in Australia for many decades. 477 MHz is the frequency band used by UHF CB radio — the current standard in Australia for recreational 4WD, caravan, and farm communication. UHF CB operates on 80 channels and offers clearer audio, more channels, and generally better performance in built-up areas. The GME AB001 suits antenna types for both systems. What is 5/16" TPI and what antennas use this thread? 5/16" TPI (threads per inch) is a standard thread specification for antenna bases. In Australia's CB and UHF CB market, the 5/16" antenna thread is one of the most common standards, used by GME and many other antenna brands. Before purchasing, confirm that your chosen antenna has a male 5/16" TPI base thread to ensure it will connect to this base correctly. What mounting style does this antenna base use? The mounting style for the AB001 is not confirmed in the available supplier data. Common antenna base mounting types include magnetic (non-permanent, sits on the vehicle roof), gutter mount (clamps to the door or window gutter), body hole mount (requires a drilled hole), and stud mount. Confirm the mounting method with GME or your supplier before purchasing. Is a coaxial cable included with this base? Cable inclusions are not confirmed in the available supplier data. Confirm whether a coaxial cable and PL-259 or BNC connector is supplied, or needs to be purchased separately, with GME or your supplier. Will this base suit my GME TX6160 or TX3350 UHF radio antenna? The AB001 is specified for 477 MHz UHF antennas, which covers GME's current UHF CB range. Confirm with GME that the AB001 is compatible with your specific GME antenna model before purchasing.
