In plain language: CHA EMCOMM II Product DNA: Complete System Overview keeps the entire CHA EMCOMM II V2 signal path visible so the customer knows what is included, what is required, and what can be expanded safely.

A customer should be able to see the complete antenna before buying: the radiator, transformer, feed line, return path, support, and what the package does not include.

The CHA EMCOMM II V2 is a one-pound, one-operator broadband wire system built for rapid field communication when the station cannot carry a collection of resonant antennas. Its matching transformer and 60 ft insulated radiator pack onto the supplied line winder and can normally be deployed in less than 15 minutes.

What matters for this decision

  • Its value is not one universal pattern. The same 60 ft radiator can be kept low and horizontal for regional NVIS work, raised as a sloping wire for general field coverage, or bent into an inverted-L when the site offers two useful supports.
  • Matching transformer with SO-239 feed connector, wire terminal, suspension point, and counterpoise connection.
  • Sixty feet of insulated antenna wire on the line winder.
  • Carabiner and transformer eyebolts for strain relief and suspension.
  • Coax, support line, stakes, and counterpoise are selected for the documented deployment and may not be included.
  • Use the current product listing to confirm the exact purchased variant and package contents.

Why operators choose this system

Its value is not one universal pattern. The same 60 ft radiator can be kept low and horizontal for regional NVIS work, raised as a sloping wire for general field coverage, or bent into an inverted-L when the site offers two useful supports.

Published operating reference

  • Published continuous frequency range: 1.8–54 MHz.
  • Published power: 200 W SSB and 100 W other modes under intermittent commercial/amateur service.
  • Published wire length: 60 ft maximum and approximately 35 ft minimum deployed length.
  • Published weight and setup: approximately 1 lb; one operator in less than 15 minutes.

Make the next deployment repeatable

Record product revision, configuration, wire dimensions and bearings, endpoint heights, support hardware, return path, coax and choke condition, tuner state, analyzer reference plane, weather, and on-air reports.

Boundary: Broadband coverage does not mean no tuner, identical radiation on every band, or permission to reuse the EMCOMM III counterpoise table. Follow the EMCOMM II V2 configuration and return-path instructions.
Keep the current guide with the station.

This lesson explains the operating choice in plain language. The current guide still controls assembly, dimensions, power limits, and safety.
