Magnetic Antenna Base with Coaxial Lead and Plug No-Drill Mounting for UHF CB Antennas, 5/16" TPI Thread

Product Overview

The GME AB406 is a magnetic antenna base for UHF CB and CB antennas, supplied with a coaxial lead and plug. The magnetic base provides a quick, non-permanent antenna mounting solution on any ferrous (steel) surface suitable for vehicles, machinery, or any steel surface where a permanent drilled mount is not desired.

The 5/16" TPI thread accepts standard Australian UHF CB antenna whips. The included lead and plug allow direct connection to the radio's antenna input without additional coaxial assembly.

Features & Benefits

  • Magnetic mount — attaches to any flat steel surface without drilling; suitable for temporary or semi-permanent antenna setups on vehicles, sheds, or machinery
  • Coaxial lead and plug included — ready to connect to a compatible radio without purchasing additional cable or connectors separately
  • 5/16" TPI thread — accepts standard Australian UHF CB and CB antenna whips using the 5/16" TPI thread standard
  • Non-permanent — the magnetic base can be repositioned or removed without damage to the vehicle surface
  • Genuine GME accessory — manufactured by GME for use with compatible GME and standard 5/16" TPI antennas

Frequently Asked Questions

What surfaces does this magnetic base adhere to?

The AB406 is a magnetic base and requires a ferrous (steel) surface. It will not adhere to aluminium, fibreglass, plastic, or other non-magnetic materials. Most vehicle roofs and bonnets are steel and will work; confirm that your mounting area is steel and reasonably flat for a secure magnetic contact. Thicker rooflines or areas with internal bracing under the panel may affect magnet strength.

What is the cable length and what connector type does the plug use?

Cable length and plug connector type are not confirmed in the available supplier data. This is important to confirm before purchasing, as cable length determines routing capability and the plug connector must match the radio's antenna input. Contact GME or your supplier for these specifications.

Does magnetic mounting affect UHF radio performance compared to a bolted mount?

Magnetic bases provide a good ground plane connection through the steel vehicle surface, and performance is generally comparable to bolted bases when installed on a flat steel surface. However, very thin sheet metal, painted surfaces with thick coatings, or non-central roof positions can slightly reduce ground plane effectiveness. For optimal performance on a specific vehicle, a permanent drilled mount typically outperforms a magnetic base — but for most recreational and utility UHF applications, the AB406 will perform well.

Can this base be left on the vehicle permanently?

The magnetic base can be left in place for extended periods, but is designed primarily as a non-permanent mounting option. Long-term outdoor exposure may allow water and debris to accumulate under the base, potentially affecting the vehicle's paint. If the antenna is to remain on the vehicle full-time, a permanent drilled mount may be more appropriate.

What antennas fit this base?

Any antenna using a standard 5/16" TPI thread base is compatible — this covers the majority of Australian UHF CB and CB antenna whips from GME and other brands. Confirm your antenna uses 5/16" TPI thread before purchasing.
