6 PIECES OF 1/4 BLACK HEAT SHRINK TUBING PLENTY OF 14 GAUGE THHN GREEN STRANDED COPPER WIRE TO BUILD YOUR ANTENNA (20/40/80 FAN Half Wave Dipole) 200 FEET OF QUALITY AMERICAN MADE 5/32 BLACK DACRON ROPE. IF YOU NEED MORE ROPE, SEE OUR AMERICAN MADE ROPE PAGE. Long the standard of the industry the W2AU baluns are built to last! 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. USAGE NOTE: Since many Hams are the inventive types, it should noted that they also tend to not read the instructions and succeed in achieving their goals.
In any event, the matchbox is a tuner and all it does is make the transmitter believe it has an antenna with a lower SWR than it really has. This way it will introduce more power to the antenna than it can typically radiate. A random length antenna, one not tuned to any one frequency is a compromise antenna. Anywhere it is not resonant it will produce significant SWRs above 3:1.With 200 watts of continuous key down CW it would heat up the core of the W2AU balun, at the feed point, and damage it, but that is the extreme example. Many Hams understand this and do it anyway with care. Also, note that new solid state equipment further limits your operating options never contemplated over 50 years ago when these instructions were made. It is suggested that if using ladderline, no balun, because a balun at the feedpoint, would interfere with the radiation that the offset antenna needs from the ladderline. Instead use a W2AU 4:1 Ladder Line Balun at the end of the ladder line transitioning the ladder line to a coax entry into your shack. A 4:1 extends resonances available. Some hams use a 1:1. These are some ideas in using an offset antenna.
NEVER INSTALL ANTENNAS NEAR POWER LINES OR INSTALL IN A WAY THAT COULD COME INTO CONTACT WITH POWER LINES IF THE ANTENNA SYSTEM SHOULD FALL OR FAIL. CHECK YOUR LOCAL BUILDING AND ELECTRICAL CODES BEFORE INSTALLING.
