The guys on that video were at least somewhat protected inside the tube. Some years back, they erected a 964' lattice type tower in sections using a Sikorsky Sky Crane in Cincinnati. https://en.wikip
I am totally amazed at how concrete has weakened over the years. When I put up my 64' UNGUYED Heights tower in 1970, 4'x4'x4' was all that was required and that held a tribander and other antennas fo
In 1972, I put up a used Heights 64' tower. All their specs at the time required was 4'x4'x4' of concrete, no rebar. Actually I put it up at two different locations. It is amazing to me how the base
My quietest antenna is my 40' vertical. It is usually more quiet than anything else (500' loops, inverted Vee's, dipoles, OCF, etc. Of course loops are supposed to be quiet and verticals noisy, we al
In my view, if your antenna impedance does not match your feedline impedance, you do not have a "feedline", but rather a very large "impedance transformer. Ken WA8JXM On 10/27/18 3:23 PM, Paul Christ
I was his first 60m contact. After K1N shut down on 60m he called me and we had a nice chat. What an antenna farm he had! RIP OM Ken WA8JXM On 11/1/18 1:53 PM, terry burge wrote: This is sad to hear
Then how would ANYONE become experienced? To error is human, we all make mistakes, hopefully not fatal ones. When I was 16 years old I built 300 volt open breadboard power supplies and 2000 volt ones
You might also check the commercial movers (Allied Van Line, Mayflower, etc.) They are used to handling non standard items and might take it if they have empty space. Especially shipping out of Flo
I see you are not capitalizing "copperweld". Copperweld is actually a trademark and company name. Most of what I see advertised is "copper clad steel" and I wonder if the cheap wire we buy has thin
Cut pieces of plastic clothes hangers and drill holes in the ends for cheap, lightweight, hard to see, insulators. That's what I use for homemade open wire feedline spacers. Ken WA8JXM ______________
I recently tried the firmware update from the Rigexpert website and ended up with a disaster. The firmware update failed and now when I turn the unit on, the screen is nothing but hex trash. I tried

I could be wrong but I think the difference between downloading mail to your PC or just getting the headers and reading it online is whether you specify a POP3 mail server (downloads the mail) or IMA
60% ? That would be the ones not on the air. 30% ? Those are the ones using Baofeng handhelds with no idea what the rubber duckie does. 10% ? Those might be the ones actually using an hf antenna and
You mean back in the day when they had technical people to vet such material? Today they don't want to turn down advertising dollars. Ken _______________________________________________ ____________
I would not worry about the tower but I would determine true north when mounting a beam, not that 16 degrees will make much difference to an HF Yagi Ken WA8JXM _______________________________________
The length of coax for the phasing lines depend on the (fractional) wavelength spacing of the antennas and the pattern you desire (figure 8, broadside, carotid, endfire, etc.) so correct answers to y
FWIW, steel "pipe" is much weaker than steel tubing and will bend easier. Steel tubing is available in various wal thicknesses _______________________________________________ ________________________
John is correct that "pipe" is poor for structural use. The proper term for what you need is "tube" which is structural and available in a wide range of diameter and wall thickness. It is also availa
I can't find exact data but I think the trailing wire antenna for the AN/ART-13 was 200 ft of flexwire. If you can locate the antenna (Ebay?) that may be a source. I cannot imagine Copperweld and fle
