The GME Aerial Base to Suit AE4700 Series steps in when the original AE470x base or lead has worn out and signal starts to drop on UHF channels like 10, 18 or 40. The SO239 connector and 5 m low loss coax give you a clean run from bullbar mount back to the cab on most dual cabs with wheelbases under 3.5 m. You keep using the same AE470x whip, just with fresh hardware underneath.

The base is built around a metal body matched to AE470x antennas weighing under 1 kg and suited to mounting plates up to 5 mm thick. The low loss coaxial cable is cut at 5 m so you are not left with a massive coil stuffed behind the dash that can kink. The SO239 end suits standard 5 W UHF sets sold across Australia, so it drops straight into typical touring and tradie setups.

Q: Does this aerial base include the actual AE470x whip antenna?

No, this kit only includes the base, SO239 connector and 5m low loss coaxial cable. You reuse or separately purchase an AE470x whip antenna. This setup is meant to replace a damaged or corroded base and lead while keeping the rest of your GME gear. It is a straightforward way to tidy up signal issues caused by old cable.

Q: Can I trim the 5m coaxial cable to a shorter length?

The cable is supplied at 5m and should only be shortened by someone confident with RF terminations. Cutting and reterminating the cable affects impedance and shielding if done incorrectly. Poor terminations can increase signal loss and introduce noise. If you need a different length, it is worth speaking with a radio tech.

Q: Is this base suitable for mounting on a bullbar bracket?

Yes, this base is suited to AE470x antennas commonly fitted on bullbar brackets. The supplied 5m lead is typically long enough to run from a front bar to an in-cab radio location. Check your bracket hole size and bar layout before fitting. Securing the coax away from sharp edges will help it last longer.

Q: Will this aerial base work with any brand of UHF radio?

The base terminates in an SO239 connector, which matches many UHF radios using a PL-259 plug. Compatibility depends on the radio connector type on your specific unit. If your current AE470x antenna system uses an SO239 and PL-259 pair, this base is likely to slot into the same setup. Always compare plugs before ordering a replacement.

This antenna base suits GME AE470x Series antennas. The base and lead assembly connects via an SO239 interface. The 5m low loss coaxial cable allows routing from antenna mounting point to radio location in the vehicle cabin or console. Specific vehicle makes or models are not listed for this antenna base.
