I am going to be making a trip to the irrigation tubing supplier in a couple of days. Plan on buying several pieces for a 40m 4 square. I don't have the ambition for a 80m 4 square yet. My question i
Insulation is inexpensive, as the bottom of a 1/4-wave vertical is a low voltage point. You can use sheet teflon between the irrigation tubing [which I think is overkill for a 40m vertical] and the s
I use electrical conduit as an insulator. It also makes a great way to put a pivot point on the 4X4. I have pics if you'd like. I'm running this setup for both a 40 and 75/80 4 Square. Mine are about
Hi Doug, Two inch irrigation tubing fits perfectly into 2" PVC electrical conduit (which makes a perfect insulator) which fits nicely into DX engineering 2" U clamps. I use it for insulating the driv
What about using some PVC pipe (or sheet) as insulation? _______________________________________________ See: http://www.mscomputer.com for "Self Supporting Towers", "Wireless Weather Stations", and

These Resin Support Block Clamps are ideal and can be purchased from DX Engineering in sizes to 2 1/2 inches. Look in theAntenna Building Parts section. http://www.dxengineering.com/Parts.asp?ID=184&

Same method and results here. The bottom of the pipe is about 9 feet off the ground so if the snow gets that high I have bigger problems! Dick -- Visit "The Barnstormers Contest Group - NZ1U" website
I don't think you need to bother with insulation. I've had no problems over the past 8 years with my 40m 4-square which has aluminum tubing mounted to pressure-treated 4x4s with plumbing clamps. Each
I know you asked about the electrical issue, but at my QTH this setup is guaranteed to fall over as soon as the ground gets wet and a good wind storm happens. At least with the 4x4 sunk 4 feet into t
If he's talking about full-size 80m verticals, I would assume they would be guyed in which case 1 foot into the ground would be plenty in any wind as in this case the its only job is to carry the ver
All these threads about the 4 Square have me wondering if that might not be a better solution for the wires at this QTH, which always seem to come down for one reason or another (usually wind or ice,
