Bud Another thought. Consider using 20d Galvanized Nails and 1/4" Fender Washers. The 20d nails are .150" dia. and 4" long. The 1/4" Fender Washer is 1-3/8" dia. and the hole is just .210 inches, or
Hi Most of us who live on small city lots seem to couple a pair of diametrically-opposed words together when we consider 80M vertical antennas. The two words are "efficient (or effective)" and "small
Larry Most of what I think I know about Yagi design came from spending time with the K6STI's Yagi Optimizer design program. Clearly, any design is always a tug-of-war between front-to-back, forward g
Dan I think it's pretty clear that a beam is wind-load balanced pointing into or away from the wind, and when it is rotated 90 degrees the boom is wind-load unbalanced. The wind, however, doesn't see

Rod Our local club has used "top rail", made for fences. You are probably familiar with a chain link fence - the bar running across the top of the fence is called "top rail". Residential fences use s
Dick Insofar as supporting antennas in the trees, I used to use a line from the antenna through a pulley and then down to ground level. At the bottom, I hung a weight to keep the tension on the anten
EdWhen I replaced the awning on my RV, I salvaged the old aluminum roller. It was about 18' long and 3" in diameter. By strapping a large S-hook to the bottom, it them hooks onto and is supported by
Noel If you wish to get rid of that uneasy feeling you have expressed, I would suggest you write a confirming letter to the city planner thanking him for his assistance and confirming what he has tol
Dan I have 80M, 40M and 30M Inverted V's on one feedline. After you put them up, check the SWR and locate where they are resonant. You can then trim each to move the lowest SWR to whatever frequency
Sarky If you put the Bird Wattmeter between the PSG Power Source and the cable, and then measure forward power, P1. Then move the Bird to the end of the coax but before the load, and measure forward
Steve It sounds like power is continuously applied to the solenoid else why would it buzz when it shouldn't. A quick check would be to see if it unlatches when power is disconnected. Just a thought.
Pete When I read your query, I checked on Google using the word "knots". I was surprised to find the first site listed was titled "Knots on the Web", a 35 page compilation of books, videos, et al - c
Jason When I got a new awning for my RV, I kept the aluminum tube from the old one and now use it as a gin pole. It is 18' long, about 3-1/2" in diameter, and it light but stiff. It worked very well

Larry You might also look to your local RV outfit. I replaced my awning and used the old roller (about 20 feet long and 3.5" diameter). It works well and was "free" (i.e. all I had to do was buy a ne
Bryan Our club has put up a lot of Field Day antennas over the years, and they always seem to require several people to raise them. What I used on my RV might work well for you. It was a 22' length o
Robin When I put up an Inverted V, I always add 3-feet of wire to each end of the antenna. Then when you check the SWR and its too high, you can pull some of each leg of the antenna through the insul
