Know before you buy
No, the CHA MIL EXT 2.0 is an add-on specifically designed to extend the length of the CHA MIL 2.0 whip. It must be used in conjunction with the CHA MIL 2.0 and a compatible HYBRID series base to function as an antenna system.
When combined with the CHA MIL 2.0, the extension creates an antenna with a total length of 18 feet and 2 inches. This increased length helps improve performance across the 1.8-54 MHz frequency range.
While the aluminum construction is durable, the product is not inherently waterproof. If you plan to leave it installed outdoors permanently, you will need to apply waterproofing measures to the connections to prevent corrosion and signal degradation.
This version features thicker, stiffer aluminum tubing and a single-piece construction design. These upgrades are intended to minimize signal loss and provide greater structural integrity during field deployment.
The extension utilizes a standard 3/8-24 thread mounting configuration. This ensures compatibility with a wide range of amateur radio antenna mounts and HYBRID series bases.
