I am going to put up a 90ft Universal Tower. It has the 25" base. Being such a lightduty tower I was planning on using it for hanging wires that I pull up with a pully. I will need to fabricate some
I will be getting a 90ft aluminum tower in a couple of weeks - it will be a Universal Tower with a 26" base section. I am trying to decide on how I should use it. Having never had a tower that was hi

I have several sections of alumunum tower (Universal tower) that I plan on putting up as a 40/80 and maybe 160m vertical and plan on making it around 90 ft, including the aluminum tubing sticking out
I was thinking about putting up bobtail curtain for 40m out in my backyard. The problemis there are no trees anywhere near that can be used to support wire. If I were to put up three aluminum vertica
Someone mentioned that they poured and underestimated how much concrete they needed. Does it matter if you pour 3/4 of it and then come back in a few days or a week and finish it up? Doug, N4IJ _____
I am going put up a Bobtail Curtain, but before I do it, I want to put up an elevated vertical (low ground plane?) so I will have a comparison. I am going to use it on 40M. So, what is your experienc
Don't think I have posted this here. I have a Universal Tower (the aluminum jobbie) that has a bent 18 inch section on it. Looks to me like someone tried to repair it and failed, as they blew the wel
I thought I posted this yesterday but think I put the wrong address in. Is the Comtek box the best way to go for 4 squares? I like to experiment, but from what I have read, I need good equipment to a
I have not gotten into antenna modleing enough to have done this, but does a Discone antenna have a low radiation angle or not? I don't think I have ever heard of anyone actually using one on HF. Dou
I have a short 40 foot aluminum tower that I use for experimentation - At the moment it is serving as a 1/4 wave vertical for 80m. I has 26 ft of aluminum tubing sticking out of the top. It is insula
I looked at the manual for the HyTower trying to figure out the stubs they use. I know a normal stub would be 1/4 wave shorted on the feed side, thus acting as an open for the freq of interest. But f
Ah Yes, I wasn't really thinking - 3/4 wavelength for some of the stubs. Doug, the HyTower may be viewed as a set of verticals, one for each band, fed at a common point. The distance from the base to
I would like to protect my house from a strike if I can. Where does one find lightning rods, cable, etc? All of my antennas are far from my house so they do nothing as an umbrella. Doug, N4IJ _______
I have 40ft of the Universal tower on the ground and I would like a couple of straight sections to add to it to extend it at least 10 more ft. before putting it up. The base is a 26 inch section. If
Someone mentioned to me in an E-mail that they were using the falling derrick method of raising their Universal tower (aluminum). Can they, and others give me ideas on how they do this? Material for
I have heard that comparisons of 4 square systems showed that ones that were ground mounted with radials performed better than those that are elevated. True? Doug N4IJ _______________________________
I would like to buy one or two sections of Universal tower aluminum tower sections. Is it economically feasible? I mean, isn't there a minimum charge for trucking? Are there other ways of shipping so
The answer is - it will cost me about $120 for shipping a couple of aluminum sections if I pick up at the terminal. Not as bad as I thought. Doug N4IJ _______________________________________________
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
I just bought 5 pieces of 2 inch diameter 30ft long irrigation tubing. I found a farm supply place in Farmville, VA. There are probably these types of places in most states. I was sort of interesting
