DATA

 

The HE-0580-10 is a high power, right hand circularly polarized (RHCP) severe duty small
antenna for both military and commercial applications.

 

The antenna is constructed entirely of aircraft certified 6061-T6 aluminum and G-10 fiberglass
with copper radiator in a 100% sealed radome.

 

This antenna was custom matched from 5.0 to 6.0
GHz to have the lowest VSWR possible, achieving a 2:1 VSWR across the band.

 

The antenna is designed to provide many years
of service.

DATA

 

The HE-1000 series antennas are high power, wide band, severe duty antennas that can serve both military and commercial applications.

 

The antennas are constructed entirely of aircraft certified 6061-T6 aluminum with copper radiators all enclosed 100% sealed radomes.

 

They are available as a single helix or as a pair, dual mounted on an antenna tower.

 

These antennas will provide years of trouble-free service in the most severe environments and are currently in use by several U.S. Military installations in remote locations.
