W6SAI OCF Dipole 40-6 meters antenna legal limit Unadilla W2AU W2DU
A RF choke is used to prevent or reduce common mode. Currents passing down the feedline.
Directly after the 4:1 balun. W2DU In-line choke is used. The feedline tap point is at 20.5% from one end which gives a good match to 200ohms on 40m to. Each connection is soldered, crimped and covered with adhesive lined heat shrink 3:1. The dipole is constructed using top quality, FLEX-WEAVE TM is a sophisticated hybrid aerial wire. Its new innovation provides rope lay construction strength and high flexibility. It can be tied in knots to insulators and untied for repeated use.FLEX-WEAVE TM is sometimes referred to as "wire rope" or "jewelers rope". It will not kink or rust out as will copper-clad wire. This flexible wire has also been used for rapid deployment, spool-out, military aerials.
FLEX-WEAVE TM #14 (168 strands of #36 wire). It is excellent for quads, dipoles, long wires, and rapid deployment (spooled-out) antennas. Highly UV resistant PVC jacket.
FLEX-WEAVE TM is the "Cadillac of aerial wire". It has been written about in all amateur radio publications since its introduction in 1989. This revolutionary product has been used by thousands of hams, commercial firms, and government agencies.
The insulation has superior abrasion resistance for running through trees and is UV and weather resistant for use on the seacoast or in other harsh environments. They'll stand up to acid rain, high wind loads, and high snow and ice loads. The W2AU is the preferred Balun of Amateurs worldwide. W2AUs operate at a low VSWR from 1.8 to 40 mHz, and handle powers up to 2 KW PEP (at SWRs of less than 3:1). W2AU Baluns are transformer designs with ferrite cores to provide 95% minimum coupling efficiency.
Each has a built-in lightning arrestor, hang up hook, and 600 lbs of pull-apart strength in a weatherized, rugged package using only stainless steel hardware and quality materials. The 4:1 matches 50(75) ohm unbalanced coax to 200(300)ohm folded dipoles.
SWL Can be used as a off center fed shortwave antenna to provide continuous coverage from 500 kHz to 60 MHz. No trimming - fully assembled, complete and ready to install.
