Ken--the cheapest way to do this from my experience is to buy a shipboard container and outfit it the way you want. The cargo containers are typically made of steel although aluminum (armored) and fi
Jose-- I am sure that Jose will be well taken care of. I was very impressed with the service from Gianni when I was working on a PST71 for A61AJ. Gianni was very helpful in making some changes for u
Sounds like Phillystran to me--and in the old days KLM supplied Philly with their antennas and used a little plastic block with (about) 5 holes in it to use as an end termination. The core is not fib
Current Philly products are now somewhat different than the older product that was supplied with KLM antennas--mostly having to do with the jacket thickness. So OD of the jacket is not a good correla
Nick-- I am just finishing putting up four of the HD versions (125 MPH wind rating) of this antenna for a marine application in Rhode Island. (Also putting up four of the 6-10LP5s.) They are certainl
Here are few observations to add to the discussion based on my experiences in radio astronomy. Gold-plated DowKey coaxial relays are not reliable on reception unless you take special care when using
Here is a note I posted over three years ago. Thought it might still be relevant, so I decided to call the company and confirm a few things. Their phone number (area code) changed since the original
When I mentioned radial systems in my note on the Copperweld source, I was thinking in terms of the elevated ground plane "radials" that AA0RS uses on his 160M 4-square. An application that suggests
You want to talk cheap?? Take your old SS hose clamps that you have stripped out and throw them in a box until you need some stainless scraps. Tin snips will cut some pieces from the old ones and you
Your question makes it look like I suggested using stainless steel wire--but it was not me. It was Henrik, OZ1ING, who made the suggestion. I would not recommend it for a number of reasons-- not to m
Are you familiar with the NY-LA-BONE, the nylon chew toys for dogs?? The coyotes around here think that coax and control cables are chew toys. The chew up surface cables into 6 inch lengths. But bury
I believe all electronic-color-code tapes ARE available from electrical supply houses. Usually in a 3-M display and I think they are Scotch-35. Similar to Scotch 33+ I have used them in the past and

Don, VE6JY-- I agree with you on the cheap colored tapes from Radio Shack, etc. But the Scotch 35 colored tapes perform as well as Scotch 33+ and 88. Remain flexible and no gooey-glue syndrome after
And here is my shoe tip-- About 20 years ago I bought a pair of Lineman's boots from Sears. These are for use on utility poles, with or without steps. When used on poles without steps then hooks, cli
Just a bit of caution on top rail for chain-link fences. Some of the stuff that I have seen is made from a long strip of steel that is rolled into a tube and then hot-dipped galvanized without the be
I have used irrigation tubing for a number of vertical projects in years past. There is some decent stuff out there and some pretty lousy junk. It is probably most available from the irrigation suppl
Bob-- That was NOT a professional installation--I don't care WHO did it. OLD Rohn catalog shows 3 -- 5/16" dia x 2-3/8" long NC bolts and 3 -- 7/16" dia x 2-1/4" long NC bolts per Rohn 45 section. Ro
