Thought of one more thing. Are you sure the tips of the elements are 3/8? Or are they 7/16? HyGain has long used 7/16 for element tips combined with their swaging methods. Just a thought. Ken K6MR Ba
The only HS tower Ive ever seen in the wild was owned by W6YI back when he was WA6EKL (late 1960s). Could have been a HS-354 or a 471. As I remember the whole line of TriEx guyed towers, they made a
I use three loops, and have the rotator set at the loops tightest point (depends on which way you wrap the loops) when installing. The loops change size very little when rotating so no risk of snaggi
Theres no magic or guessing necessary. Get the software that calculates the forces on the mast and tower and make sure you dont exceed the rated capability. Towers are rated for so many square feet i
Yes you are correct. Ken K6MR Happy New Year! I have 2 SureFire Radio Automatic Band Pass Filters that I need to make cables for and have a question about how to wire them. My Elecraft K3S 15-pin acc
Sounds like an excellent modification. My question is what failed in the prop motor? Did something actually break? The material in a prop motor is exceptionally strong, and I cant imagine any kind of
We always found the spline/sockets at wrecking yards. At least at that time there wasnt much call for them and the one yard we used always had a good supply. And the exact model isnt critical as long
Ah yes. Water is the one thing that will kill a PP. I haven't checked lately, but all the internal bearings were still available as of about 15 years ago. The only one I could never find is the th
Climbing a W braced crank up (Tri-ex/Tashian) is no different than any of the W braced fixed towers like T-15/T-20/T-26. Weird yes, but with climbing boots its not a problem. Just put some big pipes
Yep, I know it can happen. I knew a kid that had that happen just after getting his new crank up. We always called him Fingers from there after. I was in the antenna business (worked for a TriEx deal
The EHS tails are completely useless in a serious fire. When the flames are 100 feet high, nothing survives. Been there done that. Ken K6MR and careless gardeners :) I dont think the last fifteen fee
Thats something Id almost pay money to do. With all that hardware you are safer there than on a six foot step ladder ;^) Ken K6MR Airline ad.mp4 If you're afraid of heights, do not watch this. It's a
Ill bet they had a direct line to the weather guy to ensure they had the best weather possible. I did notice that the air quality there looks pretty bad. Almost as bad as we have in California these
Did you catch what looked like a little graffiti in one shot? Maybe those who get there leave a little note that they made it. One unusual thing (though I guess for this kind of structure it makes se
Thats the original HyGain RotoBrake controller. A little tough to interface directly to anything else because it uses a 400 cycle selsyn with a 5:1 gear train. Very nice display though. Of course now
According to the inflation calculator this would cost $1800 in todays dollars. Ken K6MR Hello All, See Attached from the 1962 Arrow Electronics catalog!! Ted K2QMF Thats the original HyGain RotoBrake
How do you get a beta match to work on all bands ? Hygain also does it on the TH7, so the secret must be out. Ken K6MR Meanwhile, Mosely is still blathering on about... establishing 52 ohm resonance.
Even the original TH6 with the single driven element had the beta match. I think the TH3 did also. That must have been a bunch of trial and error since the TH6 has been around since the 1960s and I t
AC6LAs AutoEZ does exactly that. Would not leave home without it. Ken K6MR AO was great! The program allowed you to use variables for the wires so changes could easily be made plus you could optimize
The C3 is 7 elements, where 10 meters is a two element. The C3E has a 10 meter reflector, so its three elements. Here Im counting the double driven element for 10 meters as one element since its just
