Use a carpenter's square and mark a straight line across the boom at each mark. United States Rope tested my 10 year old line and found that although it was getting weaker, it still met the service specs I needed, so it was not about to fail. Brass hardware can be used for electrical connections where there will not be much mechanical stress. Flux paste on the connector's flange will aid solder bonding. Then put your sensor on the dummy load end. The experts at M2 Antennas know and understand radio propagation. After removing all the corroded and rusted hardware and traps and giving the elements a good acid bath, brushing and sanding, I had the makings for free for either a 15 or 10 meter beam for modes A, K or T.

Once you pick up a few tricks and skills you will agree that installing "N" connectors on is much easier and less lossy than using the standard so-called "UHF" PL connectors. Also the "good" sections had higher losses than shown in coax attenuation charts. Picture a degree circle with 0 degrees being due north, west, south and 90 east. If you have never done this you may be in for some surprises. This same store sells cheap coax connectors that have higher impedance bumps SWR and losses than my Amphenol connectors.

You may instead use any screws with a large head or a screw with a flat washer. The formula for the step-up ratio, r, is also shown.
Description: Run a solder bead along the screen's edges and reinforce ground attachment points where the screen can be screwed to existing cabinet screws. Tuning is of course by adjusting the lengths of the dipole elements making them either shorter or longer as needed. Never install antennas near power lines or in any location that would place people or pets within the near field radiation pattern of an antenna.
