Hazer for Utility Pole?
A friend gave me a forty foot Utility pole. Since I am not a climber I
have not determined how to make the best of this in my continual antenna tinkering. I keep coming back to the hazer transit method. The device would be complicated by the fact that the pole is about 12 inches in diameter at the bottom and 6 inches at the top. I expect to bury 5 feet of it. I hope to construct the device so that there is NEVER a need to climb the pole. The galvanized wire rope on my Crank up mast that I purchased in the late 1970's is still looking fine. Any experience or ideas are appreciated! BTW, Any idea why this tram mechanism is called a "hazer?" John Ferrell W8CCW |

John Ferrell W8CCW Hazer is a brand name of GlenMartin towers: http://www.glenmartin.com/catalog/page10.html, maybe it was the guy that originally designed it, or it could have just sounded neat to marketing. what type of antennas are you planning on putting on the pole? personally i would put a couple of good screw eyes with pulleys and run some decent rope through them and use it for wires. |

I think the word "Lift" is probably the most accurate term to use. There is a good series on YouTube referring to "AntennaVater" for the same type of device. I want to keep the structure as general as possible so I can continue to experiment with a broad range of Ham antennas from DC to light. I shy away from rope because of the limited life expectancy.

John Ferrell W8CCW Limited life expectancy????? I am still using some ropes I bought in the 1960's. Some type of synthetic material nicely woven into a 3/8 inch rope. You need to investigate further, or buy some better class of rope! Paul, KD7HB |

Paul, KD7HB agreed. for something not accessible like that you need decent uv resistant dacron. that is readily available and lasts for many years under load. Check it periodically for wear and pull replacements up as needed without climbing. if the pole is going to have cables running up to feedpoints then use wire rope, just be sure to use big enough blocks with the right materials. |

Paul, KD7HB I will keep that in mind. I have about 250 feet of blue 3/8" Nylon that was my primary anchor rope from my sail boating days. It has served from time to time as a temporary guy line for ham radio. However, to hoist the fixture a winch with a brake sounds more convenient. John Ferrell W8CCW |

John Ferrell W8CCW John, I think my ropes are dacron, as mentioned. That stuff really lasts!!!! I still have two dacron sweaters my mother bought for me when I started high school back in 1953. Still fit and have never worn out. I haven't seen dacron ropes for a long time. Paul, KD7HB |

The Glen Martin hazer looks like (I've never seen one in person) it uses the tower as a track, and the constant cross section is key. The taper of the utility pole sorta kills that idea, so maybe some kind of curtain track turned vertical is what you need, something industrial like the kind used in theaters. Bolt it straight to the pole and fabricate a trolley to carry a rotor, thrust bearing, etc. Once you get the trolley to the top wrap the cables around the pole in a spiral to keep them from flopping around in the wind. I'd use a galvanized wire rope as opposed to something plastic to pull and hold it up. BTW, Any idea why this tram mechanism is called a "hazer?" John Ferrell W8CCW I have no idea at all, I thought it might have been something nautical but dictionary searches don't show that at all. - Galen, W8LNA |

Paul, KD7HB Sure, you've seen Dacron ropes, just not under that name. *Dacron is a trade name for a particular form of Polyethylene Terephthalte (PET), aka Polyester. Beverage bottles are a big use of PET, but a lot more winds up as fabric or rope. *In film form, one trade name is Mylar. (originally, it was called Terylene, but Dupont called it Dacron, probably because it sounded better, and it was similar to Nylon, another Dupont product..) You see it labeled as "polyester" rope these days (probably because DuPont's patents have expired, so anyone can make the stuff, but only DuPont can call it Dacron) Thanks, Jim. Paul |

I think that is the way I would go. Jimmie |

John, it will probably be easier [rather than redesigning either the pole, or a hazer] You can find plans for planting two sections of a powerpole, spaced slightly on each side of your pole. Those to be used as the 'base' for your pole to be sandwiched between. You want the base poles to be reasonably tall, to allow your's to be pulled to the vertical. You'll need substantial solid diameter rod, for your pole to pivot on. Don't forget to include a 'over-travel' stop, and a means to secure your pole in place once swung up into vertical. There are photos of such antenna supports in Ham Radio references circa the 1930's and later. Remember you MUST periodically treat wood with anti-termite chemical. Approach your local telephone and/or electric companies for a source of pole material, and perhaps they'll even be able to place your base & swing-up section [for a fee ?]. All told, it might be more economical to buy a used tower in GOOD condition. |

All told, it might be more economical to buy a used tower in GOOD condition. Part of the problem here is that I failed to heed the old advice "Be careful of what you wish for, you might get it!" The pole was a gift from a friend in the construction business. I never dreamed he would come up with it until one afternoon he showed up with it at my house. I live in a rural setting with my house in a 3 acre field with trees down one side and across the back, a lane down the other side. The house is set back 120 feet from the road. Being zoned agriculture means pretty much free from regulation. I feel obligated to at least make an effort to take advantage of these circumstances... Since I am now 70 years old, this thing does not have to last forever and the pole seems to be nearly new condition now. As I see it at this point, I intend to set the pole 5 feet in the ground far enough from surrounding structures so that a fixture with a rotor platform can be hoisted and stabilized into operating position with an electric winch. I will endeavor to use as much as possible from my existing stock of "junk" rather than accumulate more. Perhaps what I learn & share will be of benefit to others in the future if only as a bad idea. Please keep the advice coming! John Ferrell W8CCW |

A lot of the temporary job-site companies (e.g. Andy Gump, here in Southern California) that supply restrooms, power, etc. can plant a pole for you. Cable TV companies plant a fair number of poles, but almost universally hire contractors to do it, so what you'd need to do is find the contractor. Watch for their trucks. |
