SE-2H: 2 Meter Halo Antenna
The SE-2H, 2-Meter Halo covers 144 to 146 Mc. at 2:1 or less VSWR. Heavy Duty construction that allows 120 MPH
wind survival with 1/2" radial ice. Halo antennas are great for net control operators and for beacon operation, where an omni
directional pattern of operation is desired to reduced the need to swing a directional array to make a contact. The SE-2H is
constructed of aluminum, fiberglass, UV resistant PVC, and stainless steel components for years of trouble free operation. The
SE-2H is designed to be mounted horizontally for CW/SSB operation, and is equipped with a Direct DC Ground for effective
static dissapation. Built for fixed station use, the SE-2H can also be used for portable, mobile or rover operation.
Mast mount is designed to accept sizes between 1" to 2" OD. May be stacked with a phasing harness for higher gain (+3 dB) fixed
station applications. Equipped with a SO-239 (UHF Female), or an optional Type-N connector.
