241. Re: [TowerTalk] Source for Radial Wire...was Elevated vertical (score: 1)

As the current in each radial is small, even at legal max power, you can use insulated #18 which is available on very large spools at ebay. Last spool I bought had 15,000+ feet for less than $20 SHIP

I've done just that using fiberglass rod to insulate the tower from the base. The rod is available in all diameters, so you should be able to find the right size. Just drill holes through the rod tha

Sounds like the Drake remote switch. Not sure of the model number/designation nor where you could find a manual, but Drake made a few of those before they went belly-up. Don N8DE ____________________

Jose, I suggest you keep the KLM exactly as it is.... very broadband and excellent f/b with good gain. You won't approximate the f/b and broadbandedness with a single driven element. Just my 2 kopeks

Purchase a long, round file that you can mount in a hand-held drill/driver. Use it gently to remove the crud. Then .. use NoAlOx or some other anti-oxidant between the element pieces. Good Luck Don N

5.5 square feet? Do you mean CUBIC feet? If so, that is definitely NOT enough concrete. 5.5 Cubic YARDS makes more sense to me, as my Universal towers ALL have from 4 to 6 Cubic YARDS of concrete bel

Some thoughts on this: Do you have a basement? How about vents in the basement walls? You could replace a vent with a panel that has feed-throughs for coax and control lines. You can then run the lin

Eric, As an owner of 5 Universal towers, let me try to help. First, do NOT use the B-22 base if you intend to go higher than 40' at some future time. Use the B-26 base with 23-40 tower composed of 26

Tom, Why not put the three verticals in a right triangle. You can remotely switch the phasing using voltage over the coax so it will beam four compass directions. Mine were [and will be soon] phased
