GME AD201 Male to Male Antenna Thread Adaptor 3/8" to 5/16" for 27MHz CB

A genuine male to male antenna thread adaptor from GME, the AD201 converts between a 3/8" thread and a 5/16" thread specifically for 27MHz CB antenna installations, bridging thread size mismatches between older 3/8" hardware and the standard 5/16" TPI antenna whip thread.

Product overview

The GME AD201 is a male to male antenna thread adaptor that converts between a 3/8" thread and a 5/16" thread, specifically for 27MHz CB antenna installations. Both ends of the adaptor have external male threads, a 3/8" male on one end and a 5/16" male on the other, allowing connection between components where thread sizes need to be bridged.

The 3/8" thread was widely used in older 27MHz CB antenna bases, certain marine antenna mounts, and some aftermarket bull bar and gutter mount hardware. The 5/16" TPI thread is the Australian standard for CB and UHF CB antenna whips. The AD201 allows a 5/16" male-thread antenna whip to be used in a 3/8" female-thread mount, or bridges other 3/8" and 5/16" mismatch scenarios in 27MHz CB installations.

Features and benefits

Male to male configuration: Both ends have external threads, bridging female-to-female thread mismatch scenarios in 27MHz CB antenna installations.

3/8" to 5/16" thread conversion: Allows connection between components using these two different antenna thread standards.

27MHz CB specific: Designed for 27MHz CB antenna installations where 3/8" and 5/16" thread hardware needs to be combined.

Genuine GME accessory: A manufacturer-supplied adaptor ensuring correct fitment between the two thread standards.

Compatible with

The AD201 is compatible with 27MHz CB antenna installations with mismatched 3/8" and 5/16" thread components, including GME 27MHz CB antennas using 5/16" TPI thread base and 3/8" female-thread antenna mounts used in older 27MHz CB systems and certain marine hardware.

Frequently asked questions

What does a male to male adaptor do in an antenna installation?
A standard antenna installation connects a male-thread antenna whip into a female-thread base. A male to male adaptor is used when two female-thread components need to be joined, for example connecting a 3/8" female-thread mount to a 5/16" female-thread extension or coupler. It effectively extends the male thread in two directions, bridging two female sockets of different thread sizes.

What is the 3/8" thread standard and where is it commonly used?
The 3/8" antenna thread, sometimes listed as 3/8"-24 UNF, is common on older 27MHz CB antenna bases and mounts, certain marine antenna hardware, and some American-standard antenna equipment. It is a larger diameter thread than the 5/16" TPI standard used on most Australian UHF CB and CB antenna whips.

Is the AD201 compatible with 477MHz UHF CB antennas?
The AD201 is specified for 27MHz CB antenna installations. Whether it is suitable for 477MHz UHF CB antennas depends on the specific antenna whip and mount thread specifications. Contact us if you intend to use it with a UHF CB system.

How does the AD201 differ from the AD006?
The AD006 is a male 5/16" to female M6 adaptor for SCANIA and IVECO heavy vehicle antenna mounts. The AD201 is a male to male 3/8" to 5/16" adaptor for 27MHz CB installations. They serve different thread conversion needs for different applications and are not interchangeable.

Is the AD201 sold as a single piece?
One adaptor is included per purchase.
