The CHA EMCOMM II Antenna has been specially designed for backup emergency HF system 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 is 60’ long and covers 6M to 160M. An external tuner is required.
The antenna will perform very well with a sloper or an inverted “L” configuration. For a NVIS configuration (40M – 80M) the antenna must be installed horizontally with the ground and elevated between 9’ and 12’ high.
The CHA EMCOMM II do not required any ground-plane but will perform better with one. A ground terminal is available for that purpose.
