Cheap alternative is to use black latex driveway coating. I have used that on my bamboo spreaders, lasts long time and cheap. You can fill tubing or trough with it and dip the rods in it, hang it to
torque Too complicated. I have built 62 ft booms for my Razors (Quad Yagi combination) using only one philistran guy on the top. Guy was attached about 2/3 out at the half of the boom and at the mast
Yes. Another alternative is to try slinky beverage, but flag/pennant might be the best solution with slinky running in your longets space direction. I used temporary beverages running by the curbs on
If you have piece of old conduit, cut slice of it, then cut patch about 1/4 of the perimeter, make sure the patch piece is bigger than hole. Use PVC cement (it softens the PVC) smear it on both piece
lightning MMDNV! Back in Toronto it really striked me when I upgarded from 65 ft tower with TH6 to 110' Bertha with 3 el. full size stretched Telrex 40m beam or pair of 62 ft Razors. With old tower I
I would like to see or hear that it is a fact. Any actual experiences out there? Based on my experience with insulated wire Quad elements, it works NOT. Insulation didn't seem to do any good. The top
Terribly sorry to learn of Steve's tragical end. One of fine and devoted contesters. I remember good times way back at Dayton hospitality suites with Steve, then WD8IXE and Walter, VE3IXE (ex OK1KPR)
First question is what are you trying to achieve? Contests installation, DXer or casual? Then looking at your situation you should decide what is the best, most effective (cost and DX wise) solution.
not you in You welcome! What is the reflector coming to? (:-) Yuri p.s. you would have replied, but checking with my lawyer to see if I would violate any law by doing so.
Thanks for the "picture" Greg! Looking at some of the commercial monsters, you almost have to be superfly to do the work on them. Our ham towers are toys and we try to do as much as we can ourselves.
I thank you for your evaluation, it must be based on deep knowledge of the subject. I trust you have used all this time to calculate the forces, stress and deformation/breaking points and arrived at
There are some, but.. trying to "program" or forecast propagation is like trying to predict weather. We just had last week prediction of gloomy rainy wx for weekend, but were blessed with fine sunny
What Interesting. See if you can model feedlines from antennas that are connected by their shields (as just about all antenna switches do) and their centers open and/or shorted, and the combinations.
stub, I think that was the result of our verbal barrage at the time. One thing is to claim certain performance (theoretical ?), another thing is to see the results and measure it. Even using current
strength for That is nonsense! If the guy wires can hold the load, the tower will be stressed less than if self-supporting. When you have self supporting tower, one side gets stressed on "pull" while
So you are saying that self supporting towers have "weaker legs" than guyed towers? Look around! Again, with guys, legs in the self supporting tower share the vertical load. Yes there is some additio
I find it amazing that someone would call engineer ENG-A-NEER without knowing his background. It is called self-supporting tower, it does not need to be guyed if it is loaded with design load and und
Nice thing about using self-supporting guyed tower is that you can have one set of guy wires about 2/3 or 3/4 height up, you can drop them down when calm wx or working on the antennas (no interferenc
