Does anyone recognize this tower and does anyone know where I can find more information about it? I received is as a crank-up tower. The tower sections are make of aluminum, but the pieces that made
Hi Randy, You were right, its an old Heights Tower. They beefed it up on their later models. After reading their documents I don't understand why we don't see more of these tower. They are un-guyed s
I use pvc insulated 14 AWG for all my antenna installation when I "do" wire antennas. I used it for dipoles and for ladder feeds and have had no problems. It is a little heavier and has larger area t
And I second Jim K9YC, The current that radiated is on the outside of the shield and that current has to come from somewhere. In most cases it comes from the junction point at the antenna. If you hav
Ben there, done that! The change in the SWR due to outside current on the coax is due to the change in impedance at the feedpoint. The coax acts a an extra radiator for your antenna and any change th
Hi Frank, I believe that indicate your nearby ham already exceeded the weight limit on his tower. You should have some extra marginal (read: safety factors) whenever you build a tower (or anything el
I am glad to get this information. The Height tower I have in my yard just now is old. I noticed that some of the weld or the Z have opened and was going to fix that before I put the tower up. Now I
There is no "inside". The weld is only on one side of the Z. The other side is just the Z-rod touching the leg. Hans N2JFS ____________________________________ From: Cqtestk4xs@aol.com To: towertalk@
Hi Terry, have to give you a comment here: We, my family, moved in to a 200 years old house 1997. In 1998 it was hit by lightning and bunt down to ground. We rebuilt the house and, for obvious reason
Hi Michael, Dave, K1TTT, gave me the advice to tape the coax to the tower legs. Just plain, good, electric tape. You should, of course, us some flexible coax at the point when you need the flexibilit
The tower I am in the process of setting up was a crank-up in its past time. It had an arm sticking out horizontal at the top of the top section. I was told it held a wire to which the coax cables we
Hi, I saw someone using a arbor. There are rather large sizes available. I don't remember who used it for digging all holes for his antenna. I think it was on the Heights Tower's site. Unless the hol
How about adding a coil to your feed point. That way you get a simple antenna tuner that can tune most anything. I any using that all the time for my LW-s, ladder fed Windom etc. A 600 pF together wi
Hi Dragonsong, I believe the rebar cage will be totally isolated from ground as it is surrounded by concrete. The concrete is a relative good electric insulator and will therefor not be good for grou
Now I wonder: The concrete is conducting due to water content and then we drive in a few grounding rod and connect them to the tower. Knowing the rod are make with a copper layer and the rebar are ma
I am not an expert in this but find the comment about concrete interesting. Thanks! ____________________________________ From: jimlux@earthlink.net To: HansLG@aol.com CC: towertalk@contesting.com Sen
Wonder if that is constitutional. How are we suppose to follow something that is not even in the hands of our government. Finally ONE good thing about living in a socialistic state (which I don't do
Hi Art, Having built a few houses I am concern about "just" attaching a tower to the house especially to the eave. You could have some steel ribbons attached to the roof rafters inside the house to c
The ladder line has an electric field surrounding it. If this field penetrate some lossy dielectric next to the line(like soil) you will get losses. If you do this in a big enough pipe, such as a 4"
Magnetic wire is available in all sized. If you try to put down a #30 you might not find it after some time but #18 and up should stay for some time. (I have some #8 and that will last for a long tim
