Steve: I hope you did not make that fatal mistake with BX towers and have it hot dipped. Amazing how quickly those little aluminum rivets melt in the tank. 73 bob de w9ge ____________________________
You left off the "other guy"...K0XG rotating tower systems. I have been very happy with Richs products. WWW.K0XG.com 73 bob de w9ge _______________________________________________ ___________________
Safety wires on a shackle are easy and a wise thing to do. That said with normal guy wire tension I doubt one would ever back out unless you forgot to tighten it in the first place. Shackles are rela
Its fairly obvious that the gal on the bottom really really did not wish to be there. Its called a death grip by some. A very well done little ditty. 73 bob de w9ge www.tmedlin.com/misc/100k%20video/
Commscope is a bit less expensive, at least via The RF Connection. I'm very happy with the CommScope LMR 400 equivalent performance. I have not researched nor tried the Belden LMR400 equivalent. 73 b
I have a cat line running between one of my towers (rope at 80 feet) and a large Tulip Poplar (rope at 110 feet). The line itself is something over 100 feet long. It is 5/16 double dacron and has bee
My 2800 Orion DC turns an entire tower loaded with two OptiBeam OB16-3's, an OptiBeam 2 el 30-40 and a 2 meter stinger at the top. No problems at all. Thats in excess of 30 sq ft of windload. The oth
Better to have the mast slip than have something break. My solution to this problem is to use the Green Heron Engineering controller. You just re-calibrate and do so whenever the mast slips again/mor
Roger: An elegant solution to your "real problem" ie grounding coax shield at the top of the tower. I use PL259's but the same solution works with N connectors. I use a bulkhead feedthru, double fema
I know Rob means well and we hams should be capable of "doing it ourselves" but in this day in age time is quite valuable. By the time you purchase all of the tools Rob suggests (assuming you don't h
Looks very much like an OptiBeam OB2-40. I have one with interlaced 30 meter elements. Works as well as a two element can be expected to work. I did not look at the F12 price but bet its cheaper than
Unfortunately being there first is no longer a valid reason to be there. Folks today have discovered that they are always right and can get their way if they scream loud enough. The news media is rea
Hardwood comes from trees like Oak, Maple, etc. If you don't have one then a lumber yard is the place to go. Or you could go manmade and use white or tan pvc plumbing tube. Another thought would be c
I agree with Steve Get yourself a smallish "angle grinder" electric ones can be had for 30 bux or so. If you have a good sized air compressor the air driven grinders are even better. If you are only
I put a couple of large (I forget the exact size) Crosby clips on the upper end of the Phyllistran big grip to act as an ice cracker. Can't say if it works or not as I have been fortunate enough to n
One well placed shotgun report with #9 shot moves Starlings or Grackles and after doing it a few times they seem to move on. I have to convince very large flocks ( ie 50,000 or more I suspect ) once
Jon: I know Ospreys are large and their nests are almost impossible to dismantle but now I have a fact about Ospreys I did not know before. Thanks for the education. Merry Christmas 73 bob de w9ge __
If anyone needs an M2 2800DC controller, I have two that I will sell very reasonably. I have converted to Green Heron Engineering boxes. 73 bob de w9ge _______________________________________________
I have an 80 meter 4square built for 3525 center. I used high quality parts, LMR400, teflon connectors et all. When it is raining/rained the initial swr reads about 2.1 to 1 on the wattmeter. After a
21 sq ft is not beyond R45. read the drawings carefully and don't forget to add in the 8 sq ft of windload inherent in the draswings. In other words, R45 is rated at 14+8 = 22 sq ft. in the last draw
