Looking for ideas for counterweights for wire verticals, one end of the rope will be at a tower and the other end will be through a pulley. The pulley will be attached to a rope running through the t
I remember reading somewhere that a cinder/cement block can be used for this. The weight is around 40 lbs....well below the working strength of most rope. Want more pull?...two blocks or a bucket fil
I've used cinder blocks or cement blocks for this. Heavy, cheap and strong enough to do the job. Be sure nobody can walk under it, though. One never knows when the rope will give way...! WB2WIK/6 "If
Not sure I understand your geometry; where does the wire vertical fit into the picture? The first step is to calculate how much tension you want in the wire. IIRC, I found guidelines in the ARRL Ante
Bill: I used flat, black rubber bungee cords to anchor two corners of my now-removed horizontal loop and for the pulley and far end of my present inverted L. The far end (non-feed point) of the L is
I have long tied the rope/cordage to a 10 to 12" long piece of 2 by 4 and run it through a `half block' an 8 by 8 by 8 concrete block, just right for a 40 meter dipole constructed of 12 AWG copper w
In some places the weights used for the old sash windows are still available. They are generally about 4 lbs each. About1 3/4 in diameter by 10in long. I used some for exercising. Chris opr VE7HCB
When I was a kid, I had an 80-meter dipole made of #12 copperweld. The weights we used then were 2-foot lengths of 2-foot diameter oak tree trunk, with a screw eye inserted. Needless to say, they wer
One of my favorites is an antifreeze bottle about 3/4 full of water, with a tiny hole in the cap, tied by the handle. About 6-7 pounds. Fill it full and it cracks the plastic when it freezes (unless
Guy A lot depends on how high the antenna is and what kind of coax you have. The more pull from the weight of the coax you have on the coax, the more counterwieght is necessary. A forty pound concret
I have used the large spring from the garage door and attach it with a safety line through the center so if for some reason the spring brakes you don't have to climb the tree or other attachment poin
I think it might be a good thing that it be attached to the tree near the weight is (the rope thru an eye) so it cannot swing to far in high winds or be too far off the ground and fall on your head.
Water will freeze here in the Northeast and split the bottle. I've seen gallon paint cans used. Just fill with rocks or cement and tie the rope to the handle. 73, Stew K3ND __________________________
Rocks work great. Wrap two or three pieces of antenna wire around one and twist together. Tie your rope to the wire. They come in an infinite number of weights and shapes to fit your needs. They weat
It's hard to beat cored brick as an antenna counterweight. The three-hole or the six-hole have many of the same advantages as rocks; they weather slowly, they are available wherever buildings are bei
Let's not forget some of us do not have a ready supply of rocks all we have on the Gulf coast of Mississippi are some Casino chips,oyster shells and lots of wind. Use the nonpoision antifreeze please
