A 135 ft multiband Off-Center-Fed (OCF) style dipole antenna that covers the 80 thru 6 Meters Amateur Radio bands, most without an antenna tuner.  Typically no tuner is required for 40, 20, 17, 12, lower 10, and lower 6 Meter bands.  A tuner is required for full 80 meter operation.  The 60, 30 and 15 Meter Amateur Bands can be used with a wideband tuner at 100 Watts PEP.  The transformer is designed with a high power dual core 4:1 balun.  This design provides a direct DC ground for effective static dissipation.  The balun housing is made with American products (except for the UHF connector) consisting of a NEMA-6 marine grade weatherproof PVC housing, plus all stainless steel mounting hardware for years of trouble free service.
 
Unlike some OCF antennas that require 20 feet of an isolation line with a 1:1 isolation transformer, the SE-OCF806 uses a Current Balun that provides RF choking by design.  This means you can mount the Balun box (transformer) and also the transmission line directly to, or adjacent to metal objects, like a tower leg or metal siding with no ill effects to antenna performance.
