60′ Wire End Fed Antenna 1.8-54 MHz

The CHA EMCOMM II V2 Antenna has been specially designed for backup emergency HF systems or permanent installation. The integral broadband impedance matching network (transformer 5:1) allows broadband antenna tuning.

It is the perfect backup antenna for apartments, condominiums, homeowners associations, deed restrictions and CCRs (Covenants, Conditions & Restrictions), ARES, RACES, MARS, EMCOMM, NVIS, First Responders, and especially for Emergency Preparedness.
The unit is totally waterproof. The antenna wire is 60’ long and covers 6M to 160M. An external tuner might be required depending on the configuration chosen.

The antenna will perform very well as a sloper or an inverted “L” configuration. For NVIS operations (40M – 80M) the antenna must be installed horizontally with the ground and elevated between 9’ and 12’ high.

The CHA EMCOMM II V2 does not require any ground-plane but will perform better with one. A ground terminal is available for that purpose.
