In order to be the best two element shorty forty, it would have to use the best type of loading. I'm no expert in this area, however I do know that linear loading efficiency can vary with the design
TowerTalk is for discussion of tower and HF antenna construction topics. Your question seems appropriate. I knew it would happen sooner or later. It old age creeping up. SRI 73 fer nw, Bob AD5VJ(AAR6
So you want to install the whole 200 foot tower in one piece? This sounds pretty dangerous to me as Rohn 55G is not that strong. John KK9A I am going to assemble a 200 foot Rohn 55G tower on the grou
It's a lot easier to set your rotator to true north when you're on the ground. John KK9A I want to know why all these questions about rotors at the base of the tower? For any decent sized tower the e

GAC3455 anchor rods are not that heavy. If it were me, I would just bend the rod to the correct position by pushing on it. Also the anchor rods should be less than 45 degrees, more likely 41 degrees.

Why would you want to tilt your tower over during a storm? The surface area is the same and it seems that it would be in a weaker position then vertical. John KK9A wondering power Can you power it wh
What bearing do you have? There's a lot of information in the archives about freeing up the Rohn TB-3. John KK9A I've got a frozen thrust bearing and it looks like all the bearings are on one side of
I know one stainless steel tower, similar in size to Rohn 45G in Aruba. I have no idea who the manufacture is. I wish mine was stainless steel! John KK9A / P40A I have received an E-mail from someone
Only one out of the previous eighteen posts on TowerTalk had anything to do with tower or HF antenna construction. Perhaps this is why some very knowledgeable people that used to be quite active on t
FWIW, I had a 350' run to my towers in Illinois. I had over 60 control wires in a PVC pipe and also various runs of hardline, including 1 5/8. I only used Polyphasers at the house enterence. My talle
I think you would have better results loading the antenna with a top hat. The hat can be a single wire going back toward the ground ( inverted L) or 3 or 4 shorter wires, similar to the way you would
I know of others that have had the cable break on US Towers so you are definitely not alone. I believe that US towers recommends replacing the cable every 4 years, although many have gone much longer
There is an interesting post about KR2Q's crank-up tower accident on the CQ-Contest reflector. http://lists.contesting.com/archives//html/CQ-Contest/2006-10/msg00106.html ____________________________
The tips on the Hy-Gain antennas that I have owned have a pretty thin wall and if they are bent and straightened they will weaken and eventually break. I would replace them. John KK9A Hello, I've jus
With a 1/4 wave sloper, the tower is the radiator. W8JI would say it's just luck if it works. John KK9A Explain this one. Built a 40 meter ¼ wave sloper Sunday. Because of a 3 element quad, I
What material are your looking for? If you are looking for an aluminum mast there suppliers in nearly every major city that will sell small orders. There is usually a lot of information in the Yellow
Going to a 3" mast should improve the grip, however before I would do that I would carefully look at the mast clamp. There has been a lot of posts about the Orion clamps slipping and the bolts loosen
Yes, you are correct. Still I think that a slipping mast is a poor installation and if it slips far enough before you reset it, the wind could damage your coax. The coax loop is only an issue if the
