Portable HF end-fed wire antenna
A portable broadband system with a defined 73 ft radiator and separate 25 ft counterpoise.
Built for a real operating goal
Carry a complete broadband wire station instead of improvising the RF return
CHA EMCOMM III PORTABLE is a complete Chameleon antenna choice for operators who want a documented path from the package to an operating HF or VHF/UHF station without assembling an unverified collection of parts.
CHA EMCOMM III PORTABLE packages a 73-foot radiator, a separate 25-foot counterpoise, and the matching unit needed for a repeatable 1. 8-55 MHz field installation. It is designed for operators who need broad frequency coverage from a transportable wire antenna and want the radiator and return path clearly defined before deployment. Use a suitable tuner, preserve the two wires in their documented electrical roles, and adapt the guide-defined geometry to the supports available at the site. For a first-time buyer, the advantage of CHA EMCOMM III PORTABLE is that the major antenna role is already defined. You are choosing a documented system for a real operating job, not collecting unrelated parts and hoping they behave as one antenna. Match the deployment, required support, feed line, return path, tuner expectations, and included-versus-optional equipment to the way you actually plan to operate. Choose it by matching the antenna's documented strengths to the operating environment: available space, support height, setup time, desired bands, tuner access, portability, and the type of coverage the operator is trying to achieve. A clear comparison against nearby Chameleon systems will help both a new customer and an existing owner decide whether this adds a genuinely different capability.

Configuration boundary: The 73 ft wire is the radiator and the 25 ft wire is the counterpoise. They are not interchangeable parts of a balanced dipole unless a separate controlled configuration explicitly says so.
