This reminds me, a friend of mine did succeed in getting his concrete for free by calling concrete companies 'til he found one willing to listen to his pitch that he's a ham radio operator and was wi
And even if Rohn 65 were as readily available as 25, there is the whole new vs. used issue. Would I buy a second-hand ladder? Would I buy a second-hand seat belt for my car if I needed a replacement?
I agree with Pete. I have seen some installations by hams that even Evil Knievel wouldn't climb. Others built by 'amateurs' are well constructed. I make it a point to never climb someone else's tower
.........and if you are looking for some real excellent deals on 1/2 inch Andrew connectors check ebay. Always lots of cheapies on it for connectors...especially 1/2 inch ones. If you require UHF con

Two sources.......Burghardt and Texas Tower. There is another alternative...Polyrod from Polygon Corp. Check the archives about this relatively inexpensive alternative. Bill K4XS ____________________
I agree with Bill......use concrete. I have seen too many installations where the tower was buried in soil and within a few years there was severe corrosion. In one case the corrosion was so bad the
I believe the 45G is only rated for 40 or 50 feet self supporting with a small tribander. Even in the smallest tribander would not be safe at 40-50 feet on freestanding Rohn 45 at the 90 MPH rating.
Lee Coax?.......good question. I assume you are using it for HF work and perhaps 2 meter repeater work. In that case I suggest LMR 400. If cost is not a concern, go with the flexible stuff all the wa
One more thing to consider.....the push on the tower from the wind trying to overturn the tower, trying to put it on its side. The higher the tower the more leverage on the base from the wind. The bi
Many guys in Florida had their entire antenna systems trashed while others not in the direct path sustained light damage. Among the stations that received heavy damage are several members of the FCG.
Use a Loos tensioning gauge. Do a search for Loos. The company is down here in FL around Ft Meyers and they sell direct. Bill K4XS _______________________________________________ See: http://www.msco
Well, the tree simply is not. It measures in the 100 kilohms and megohms. What the tree IS will determine its behavior. Just a guess here.......I would think that the type of tree would matter quite
If the thrust bearing was new when you installed it and it is functioning normally, no maintenance should be necessary. However, if you obtained the bearing used it may need some work. I have come ac
Carl Time to climb the tower to check the connections on the rotor. Sounds like corrosion. I would suggest you first check resistances with your meter on the wires coming into the shack. You can find
According to my Rohn book, the angle on the rod coming out of the ground will vary between 36 and 42 degrees, depending on the height of the tower and the amount of guys. Unless you are extremely ana
Pulling the guys in closer also increases the vertical loading on the tower, which may require increasing the size of the tower foundation, and/or checking to make sure that the tower won't buckle. A
I have often wondered if the opposite is true. If space is not a problem, would extending the guy anchors out give a better wind rating? Pulling out the guys beyond 80 percent creates another problem
I'm a little bit skeptical of this issue... a typical tower 120' tower using 80% radius for guying at 3 points is going to have a guting radius of 240% for the bottom set of guys... at which point te
