Paul, Many years ago, Dentron sold a 40m vertical just as you describe. I have 5 of them .. three are in place, and the other two are under 8" of snow. We have up to 18" more forcast for today and to
Using anything heavier than #12 is a waste of effort, money, and height. As for the radials. They never hurt, and would probably help, but, imho, not worth the extra effort. As for 'lifting' a groun
Dave, From past experience, I can only suggest the following: Find/build/buy/scrounge a length of raingutter longer than the bamboo shafts. [Not sure what band/s you are looking at, but 16' for each
Tony, Sounds like an electric fence with a leakage or discharge path. Any farms in the vicinity? How about someone with an electric fence to control predators? We have one here and it make the exact
Pet containment systems do NOT pulse. They are simple a low-power transmitter of continuous output which the COLLAR worn by the pet picks up and then switches on a mild shocking to the pet. Don N8DE
Would be glad to help, but .bmp images are awful to process. Try resending this email to the reflector using JPG pics. Don N8DE Quoting Derek Cohn/WB0TUA <vibroplex@mindspring.com>: _________________
Steve, Nowhere on your website can I find the MOST important detail of your 80m yagi: HEIGHT ABOVE GROUND. Don N8DE Quoting VE6WZ_Steve <ve6wz@shaw.ca>: ______________________________________________
Sounds like a T-Match to me. Seal the ends of the coax where the braid pigtails emerge from the jacket with RTV and you'll be fine. Don N8DE Quoting DENNIS BRICKEY <n4dd@embarqmail.com>: ____________
You will get different answers from different people depending on their success or lack of it with RG8X. My experience: Used a 100'+ run of buried RG8X to feed a 3-element vertical array on 40m using
I think you must have gotten a bad batch of tower welds, as I have had no problems like you describe with any of my Universal sections EXCEPT for the sections that were felled by tornadoes! One of th
I wouldn't put more than a TV antenna on that tower. Looking at the 'bracing' between legs, it looks very weak and a rotational torgue might twist the entire tower. There is NO cross-bracing. Not one
Roger, I've had good success using the double-core balun kit Wireman sells. Not sure why you'd have 3:1 to 4:1 SWR for a well-designed antenna, though. Make the balun 4:1 and it should play forever.
TGhe polystyrene spacer used to hold the coil in place will melt and distort under conditions which cause the coil to heat much above ambient. I wouldn't run RTTY through it above the rated power, th

Yes, but that array fell to the ground years ago. Don N8DE _______________________________________________ _______________________________________________ TowerTalk mailing list TowerTalk@contesting.
The title of this discussion should be: World's costliest yagi ARRAY. The world's BIGGEST yagi has to be the 5-el monster at 7J4AAL [which I use for my desktop on Windows!]. The link is: http://www.s
From that article: "Each of the six, 75mm-diameter boom segments measures 9M long." How does 6 x 9 = 100 meters? Don N8DE _______________________________________________ _____________________________

Heights, no. Universal, YES. Heights towers have 8' sections, Universal has 10' sections. Both all-aluminum, but with a slightly different bracing pattern. Have had a total of 5 Universal towers over
Your balanced feedline can also serve as your control lines. With no voltage on the lines, one pair of wires is selected. With +V on the lines, one of the relays is energized With -V on the lines, th
