Just put up a 80 meter dipole today, but had some difficulty with two
things: proper tying off of the lift/ support rope and proper tying off of the guys. When I say "support rope" here's what I mean: one side of the dipole was anchored high in a tree while the other from a 30' telephone pole. The tree had a pulley installed, so the "support rope" hangs down from there as well as the eye bolt from the telephone pole (support rope through the eye bolt). So, I'm not sure where or how to tie the support rope ends. Right now, on the tree side, I just have several turns around a low branch with a knot; basically the same with the telephone pole side. What is the proper way to secure the base of the supoort rope? How do I tie the guy wires? Thanks for any help. |

What is the proper way to secure the base of the supoort rope? Some people use gravity in the form of a bucket with rocks or scrap concrete. It takes up slack (or pays out) as dictated the wind or ice load on the antenna. How do I tie the guy wires? Clarify guy wires, please. I have three dipoles, none with guy wires. "Sal" |

Basically, however you have to, or can. There's not just 'one way' to
do it, it's whatever 'fits' your particular situation. If there's much wind, and if using trees for supports (for example), it's a good idea to 'allow' for some movement (as Sal said). A bucket of rocks, a bungee cord, or tarp strap can work. - 'Doc |

I use screen-door spring(s) at each end of my wire antennas to permit
tree/limb movement without stretching the antennas. You should be able to buy such springs in several strengths at 'most any hardware store (probably even WalMart or K-Mart) in the USA. If I think one spring might not be strong enough for a particularly-heavy antenna, I just parallel two springs. Of course, the springs are between the antenna insulators and the ropes used to pull/tighten the antennas. If you do use weighted buckets, be sure to tie ANOTHER rope to the bucket and a nearby limb so the bucket won't fall on someone's head if the antenna rope or wire breaks! --W0PBV. |

![]() How do I tie the guy wires? Hey OM: I see you has 2 postings here both referring to guy. At work on the great lakes shipping my foreman always called me guy. He would say hey guy do this or that. So my question are those my wires? That you call guy? I would use guy ropes rather than guy wire. although you can use wire but you better has broken it up into lots of pieces. so they doesn't resonate on the band you are operating on. 73 OT de n8zu I |

What is the proper way to secure the base of the supoort rope? How do I tie the guy wires? Thanks for any help. I use polyester dacron antenna rope. Guy wires are impractical for your application. The dacron will try to untie itself, so flatten the knot with some PVC tape to keep it from unraveling. The tree end needs a short rope with a pulley, and a counterweight on your main antenna rope. Who owns the utility pole? |
