A modular radiator, whip, or extension used inside a documented antenna configuration.
Why operators make room for it
The CHA EXTENDER 12 is a lightweight extension designed specifically for the CHA MCC and CHA PRV systems. While similar to the CHA SINGLE-EXT , this extender is optimized for applications requiring minimal weight without compromising strength or performance. Each CHA EXTENDER 12 is crafted from 12 inches of anodized aluminum tubing with a 3/8" diameter , threaded at both ends with 3/8-24 threads for seamless integration. These extenders allow operators to elevate their CHA MCC or CHA PRV by either 12 inches or 24 inches when stacked using the included 3/8-24 coupler nuts .
Quick product reference
Operator decision support
See what this product is best suited for, what the documented setup needs, and the boundaries to confirm before deployment.
Modular field systems become valuable when one carefully chosen section can change what the complete antenna is able to do.
Combine it with the specified base, loading, feedpoint, mount, support, and radial or counterpoise system.
Shared 3/8-24 fit does not by itself establish RF, power, or structural compatibility

"I purchased several of the CHA Extender 12’s, along with a CHA Spike Mount to use as a portable pole so I can elevate my antenna radial ground wire. They worked great and like all Chameleon products, the quality is top notch, second to none."
"Great quality, well-made, and sturdy extensions."
"Got this to use on my PRV and other MPAS configurations. Top quality construction and the quality you would expect from Chameleon."
"Quality product as usual. Thank you."
"The product is first rate as it usually is, what concerns me is that when you pose a question to support Don Sherman takes forever to get back. I guess I’ll switch to DXE, for better customer service!"
"Very light weight and very visible for antennas"
"Picked up a set of CHA EXTENDERs for my PRV Antenna System. It raises the height of the Antenna to allow the use of some coil options and improve the frequency range of the antenna. Well made and easy to order via the Chameleon site."
"Works as advertised"
"Fits well with other components, high quality."
"I really like these extenders and the length. My only gripe, and is probably nick picking, but threading them is a little rough."
