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! 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 |
