I've been looking at this but so far haven't found the die set for LMR-600. I have 1000 feet of LMR-600 on the way. (thanks to those who pointed out the discount places for the *brand name* stuff) al

Depending on your soil conditions it might last forever or not even a year. I thought thermite was Iron Oxide and powdered Aluminum. That stuff will go through a concrete floor like butter. http://ww

I doubt Alodine would be very effective for buried radials and it is a lot of work. The Aluminum is etched with Phosphoric Acid, thoroughly washed and then given repeated treatments http://www.rci-pr

Actually I think the old, cheap, TV towers had it right. They had a sleeve at the top and that served as a "side" thrust bearing. This is a lot more than the original question, but I thought this wou

As Dave has already said, Dimmers do make noise. Generally they are nothing more than a triac (bi-directional SCR) and create a terrible wave form. Different lights, different problems. I've never ha

They are a pretty straight forward rotator for the most part and with only a couple of exceptions use standard parts. There are differences between the old green ones and the newer ones. If you conta

The rise and fall times dertermine the frequency. The wave form is composed of many harmonics. The amplitude of the harmonics drops off rapidly with increasing frequency for a given wave form. The sh

I decided to answer this on list and it's a relevant topic and there may be others interested in what's required. My PST-61 would be about the same age. Other than the pin through the shaft I think t

That topic was on here about a month or two back. We were talking about using a spline in the shaft above the rotator. That would allow for vertical movement when properly adjusted, and allow for the

While I was in the local (Omaha, NE) Home Depot the other day, I decided to price some of their wire. 500ft of #14 was $39.99 while RG-6/U was $.06 a You sure about that 6 cents a foot? It's usually

Check with the bulk suppliers. When you can purchase Times Wire LMR-600 for about 90 cents a foot (give or take) they quit offering the generic stuff. I'm not sure what BR400 is, but list price on L

I think you'll find most wire coming into the meter and from the meter to the main panel is now Aluminum. Of course when dealing with 200 AMP plus circuits/feeds the stuff gets pretty big. Years ago

Anti seize compounds have good and bad points. They do what's advertized and you can get SS apart a year or two after putting them together, BUT when used on tower bolts that are torqued the normal

I have spent the last hour searching for information on the Orion OR2800P rotator. All I found were opinions such as "I like it", "built like a tank", etc...but absolutely no information on how it's

I asked the original question and I have the old PST-61 which I believe has nearly 6,000 inch pounds of torque. The new PST61 has about 2000 inch pounds of torque while the PST61HD has 6400 inch poun

If these are the type of connectors you are looking for, take a trip down to your local Ford, Chevrolet, Chrysler, Toyota, etc... dealer and see what they might have in stock. They might be a little
