I have searched the archives and found nothing that really answers my questions... I am building a 4-square for 40 and was looking around for cheap building materials. Home Depot has 2-1/4' 10-foot s
A suggestion- look into Rohn telescoping masts (mayybe also what RadioShack sells.) I priced 30 foot locally at $38- 40 foot at $54. This stuff has the fittings already on, and is simple push-up. Bil
Gerry, I agree with Bill about the push-up mast. The 40' one extends to 35' and you can add another 10' section of the same material and adjust the height. The added section is swaged on one end and
And to the comment I would like to add: I would fill the bottle to the top with oil, screw the cap, or push the cork back in, if you live in a climate that reaches freezing during the winter. Reason:
You are in luck! First: 33 feet is to long for 7.1 mHz. Second: get Nov. 1999 edition of CQ mag, see page 26, a flagpole antenna made of 2" EMT (aluminum conduit) (designed) 73 (= Best Regards) de:
Bill, Gerry: I had one of the RS push-up masts to support a V/UHF yagi array. The connections between sections is done with cotter pins, I substituted double 3/16" bolts and nuts. Neither provides ad

There are two types of EMT. One is rather thin-walled and is designed to bend smoothly. The other is called EMT Rigid conduit. It has most of the structural strength of Schedule 40 water pipe. (The f
I built a couple of verticals in the past out of aluminum downspout. It worked pretty darn good. Shall we say it is a bit floppy after the 3rd section, but with proper guying the stuff will stay up t
Hi Jim If there are any farmers in your area, sometimes they have some irrigation tubing that has gotten bent of smashed. That makes good antenna material and you can get it pretty cheap. Sometimes j
Anybody remember an article on a 40 mtr beer can vertical circa 1956? I tried it, had trouble raising it, but finally did. No software back then to model the thing. Radials were insufficient... never
Wish that were so around here, Tom, but I've asked customers and employees at farm supply stores around Raleigh, NC, whether they know of any for sale, and they all say no. If you have any other idea

Yup! Lyn is absolutely correct. I found all the 4"-5" and well over 25' long aluminum irrigation lines complete with spraying nozzles at a local place called Alreco(Brighton, CO). The couplings are n
Lyn: Another good source of TAPERED aluminum tubing is perhaps so obvious that it is sometimes overlooked. I suggest that you check with some of the flag service companies around the your local area.
