Tilting HAM Radio Antenna Tower - Part 1

Tilting HAM radio antenna tower. A brief video describing the overall construction of a tilting 56' HAM radio antenna tower that I built. The tip of the Comet GP6 is at 80'. A Cushcraft 13B2 is at approximately 70', a Cuscfart A50-5S is at 65" (not shown in this video), a Hygain Explorer 14 (with 40m) at 60', and an Alpha Delta DXA at 55'.

    Hi Marc, I am building a 64ft tilt over with a DMX, your video is quite helpful. How did you come up with 12,000 winch? Is the 4" falling derrick thick enough? There appears to be a bit of a wow in it, perhaps its the video angle. How much does your tractor weigh? Thanks

    • @marcinmetcalfe595
      @marcinmetcalfe595 7 месяцев назад

      Thanks for your positive comments. I calculated what the forces were throughout the system. I purchased this particular winch because it was on sale (lol) and because it was well within my lifting force requirements. No "wow" in the falling derrick but you should be aligned dead on centre with your cable as shown in my videos. Please make certain that you understand what I did at the 4:50 mark in the video. The forces transfer through the derrick by the use of a through fastener and NOT the metal thickness of the derrick. Also note the lateral guy-wires on the derrick. My tractor is a BX25. Note that during the lift and lowering sequence, the forces acting at the centre point of the bucket are not acting purely against the weight of the tractor, hence the extensive strapping to nearby trees (see part 3 of my series). Good luck.

    Marc I know I commented previously about this being the best video series out there for this application. Well by watching this series several times and consulting with a friend who is much better at math than I. I'm happy to report in late October last year we got my 60 foot tower with a 10 foot mast on top up and working. It has withstood some 90 km winds and a couple of winter blizzards so far without issue. Not worried about summer as the trees will fill in and create a wind break for most of the tower. Can not thank you enough for taking the time to do these videos.

    • @marcinmetcalfe595
      @marcinmetcalfe595 Год назад

      Those reinforcement pieces are actually the base stubs that you connect to the bottom of the tower and they go into the concrete base. Instead of installing them from the base down and installed them from the base up to reinforce that bottom tower section as it is subjected to some greater loads. I’m really not able to comment on whether or not it’s absolutely necessary. I put them in for good measure since they came with the tower kit. I think it is a good idea to do it.

    One little tip on the little tractor (I have one just like it)... Extend that backhoe bucket as far out as possible for some counter weight, and poke the teeth into the ground for some more holding. It's sometimes just enough to make all the difference in preventing the tractor from moving.

      Thanks for your positive comments. I hope the videos provide you with some ideas for your project. I don’t think I would change a thing with the base plate. I have been tilting the tower down at least once or twice a year for antenna changes and review of how things are doing. It has worked flawlessly for me so far. I think that I may build a more permanent anchor point for the falling derrick so that I don’t have to use my Kubota and deal with the more complicated rigging setup. Good luck on your project. 73 from Metcalfe Ontario Canada.

    Might some weights hanging (at an appropriate length) on another wire off the guy wire(s) opposite the gin pole make a balance so the tower doesn't slam down and wobble so badly. Others do this and have even made a perfectly balanced tower pivot using the counterwight to offset the weight of the ginpole, etc. They literally hand lower it into its final resting place an inch at a time. This also eliminates the need for a solid brace between the tower and the ginpole. See ruclips.net/video/i1apgY3Gw5U/видео.html
