SE-220M: 222 Mc. Moxon Beam Antenna
Hours: Monday - Friday
9:00 AM to 5:00 PM (CST)
The SE-220M, 222 Mc. Moxon Beam covers 219 to 225 Mc. at 1.5:1 or less VSWR. Covers 215 Mc. to 230
Mc. at 2:1 or less VSWR providing coverage above and below the 222 Mc. band. Heavy Duty construction that allows 120 MPH wind
survival with 1/2" radial ice. The SE-220M features a UHF Female connector standard. Constructed of aluminum, fiberglass,
UV resistant PVC, and stainless steel components for years of trouble free operation. The SE-220M can be mounted horizontally
for best CW/SSB operation, or it can be mounted vertically for FM operation, STANDARD. Can be used for VHF rover operation,
and strong enough to be used for permanent fixed station operation as well. 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.
