MPAS Lite · Complete Antenna Systems
A complete or near-complete antenna platform for a documented operating objective.
Why operators make room for it
Build the station around the way the mission unfolds
The operating site rarely looks exactly like the plan: trees move, space tightens, and the best path may call for a different antenna shape.
That is where CHA MPAS Lite enters the kit. The Modular Portable Antenna System (MPAS) is a concept allowing the radio operator to configure and deploy the antenna system in a variety of configurations. Some of the possible deployment configurations:
For the operator, the payoff is a repeatable system that can move from transport to setup to verified operation without turning every trip into a new antenna experiment.
