SE-2MB: 2 Meter Moxon Beam Antenna
Hours: Monday - Friday
9:00 AM to 5:00 PM (CST)
The SE-2MB, 2-Meter Moxon Beam covers 144 to 148 Mc. at 1.5:1 or less VSWR. Covers 130 Mc. to 155 Mc. at
2:1 or less VSWR providing coverage of CAP frequencies as well. Heavy Duty construction that allows 120 MPH wind survival
with 1/2" radial ice. The SE-2MB features a 1:1 Guanella ferrite torrid current balun that provides a balance
feed. Constructed of aluminum, fiberglass, UV resistant PVC, and stainless steel components for years of trouble free operation.
The SE-2MB 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
