TU all again for even more great information. One quick comment Steve, I realize the loop does not need to be in the middle of the joint. I just drew that image to illustrate what I envisioned as the
Hi Grant and tnx for the additional input & considerations. You are absolutely right and that would be a much better approach to what I have here. But based on the 20 years I have been using a simila
Grant TU for the very useful write-up and description. Yesterday before solid rain and below freezing temps set in today my wife and I managed to put everything in place and raised up both towers. Ea
Thank you Dave. You were so patient & helpful with me I really appreciated your time & assistance. I absolutely love the new setup. Oh, don't let the images fool you, there is a ton of crap, coax, ol
Ahhh, for that junction a fellow TT member showed me a super simple & elegant way to form a single loop in the rope and slip it through the carabiner then pull it back down over the top & on the oppo
Correct. What I ended up using was not a knot and why I called it a "junction" hi-hi. At this point I have learned how to tie a bowline but I doubt I could make one around myself one-handed. So here
I cannot give you a formal number from Bird but I have used dozens of these for over 30 years for tempest test applications. It would not be uncommon for a technician in our lab to use one of these s
If you happen to live in a rural area or out in the country you tend to get to know all the metal fabricators, welders, trucking firms, etc in your area. I am very luck to have met a welder who is mo
HNY to all ! I cannot think of a better time to start a new 40m phased vertical project then the dead of winter with snow on the ground (as usual I could not get to it during the summer or fall). Any
Hi there. You had it right on the nose below when you said structural. I am aware of the minute differences in radiating efficiency between a wire and length of tubing. As these are going to be eleva
Hi Rick es HNY ! TU for that advice. I need to look up the weight of the heavier duty fence pipe. As these are going to be elevated verticals which I "pivot" into place by myself I need to look at wh
Makes perfect sense Rick. It has been far too many decades since I had to take all our ME classes (like Mechanics of Materials) even though we were all EE's. You have told me exactly what I needed to
Hi Gary. Wow that sounds like an awesome vertical ! 3" is pretty darn beefy. You and Rick (and others off line) have answered my question. I mean, I could have even found tapering solutions starting
L-Com Gedas, W8BYA Gallery at http://w8bya.com Light travels faster than sound.... This is why some people appear bright until you hear them speak. Any vendor recommendations ? Tnx, Dick, W1KSZ _____
What I did was purchase an inexpensive 5" harbour-fright vice that had 2 screws hold the serrated teeth bars. I took the two screws out from each side and replaced the hardened steel tooth bars with
Hi Charlie. Yes once the bars are attached to the vice you close the jaws and the interface where the two bars meet make it super easy to start drilling. Guaranteed to find center :-) The taper was m
In an efficient industrial setting you would not believe how many RF jumpers a worker or two can churn out in an hour. Our engineering facility also had a HUGE production area (where we made all the
Would it not be as simple (at least to prove that some temperature coefficient does exist) to just take a sample core, put a number of turns through it, measure it's impedance on a VNA at room temper
We used to work with the stuff back when we certification tested Sincgars R/T's etc. There are at least 4 variants of "WD-1" wire that I was aware of. There may be many more. WD-1/TT, WD-1A/TT, WD-36
Pardon the OT post but we have so many knowledgeable folks here I was hoping I could get a quick answer. This is antenna & RF related so maybe not super far off OT hi-hi. I have a 1/16" thick 3"x3" s
