SE-DBj-2pc: Two piece 146/440 Mc. Dual Band j-Pole for travel/back packing

The ubiquitous dual band j-Pole antenna, the SE-DBj-2pc covers 144 to 146 Mc. at 1.6:1 or less VSWR and 420 to 450 Mc. at 2.2:1 or less VSWR. Heavy Duty construction that allows 80 MPH wind survival with 1/2" radial ice. The SE-DBj-2pc j-Pole antenna uses a two piece main element that can be disassembled in half to provide compact storage for travel or back packing operation. The dual band j-Pole antenna is provides omni-directional coverage for 2 meters and UHF ham bands using a single transmission line. This antenna provides a convenent interface with any dual band 146/440 Mc. transceiver using a single antenna port. The SE-DBj-2pc is constructed of 6063-T832 hard drawn aluminum tubing, and stainless steel components for years of trouble free operation. The use of aluminum tubing provides for a very light weight (1.5 lbs.) unit. The SE-DBj-2pc is designed to be mounted vertically for FM operation. Built for fixed station and portable operation. Mast clamp is designed to accept sizes between 1" to 1-3/4" OD. Equipped with a SO-239 (UHF Female). Designed primarily as a transmit/receive antenna for the 2 meter and UHF ham bands, the SE-DBj makes a great scanner receiver antenna for 28 Mc. to 900 Mc. reception.
