I was given 40ft of Glen Martin M-18 Aluminum Tower a few years ago along with the accompanying Hazer tram system. I am thinking of actually putting it up this summer. In theory with the Hazer, I sho
Whether it will take the SWR to 1:1 is a function of the step size in the tuner design (if it's a switched L and C) and the control algorithm. Most autotuners stop when the SWR is below, say, 1.3:1 o
Except for mention on W8JI's website, I haven't seen much mention of "bust open" anchors as an option for amateur tower guying: http://www.w8ji.com/screw_in_guy_anchors.htm I'd be curious to know if
Thanks, Jim: Both AB Chance-Hubbell and MacLean Power Systems sell them for utility applications: http://www.hubbellpowersystems.com/anchoring/expanding/ http://www.macleanpower.com/products/item.asp
Jim, I am not sure I agree with your statement, at least not in the case of standalone auto tuner. While I am not familiar with ins and outs of practical auto tuner design, I do presume they use a 5

I was pointing a few possible problems to show to others what can happen or give another possibility to do not put in risk life or property but what was the response? supportive? destructive? Indeed
Jim, I had somewhat the same feeling until I scrolled down to the "selfie" of the guy taken from the top of one of those homebrew 200' towers made from chain-link fence top-rail. You can clearly see
Google search did not come up with anything but maybe I'm overlooking something Tnx BIll AA7XT Spiderbeam uses insulated Wireman CQ-532 PE insulated multistrand copper coated steel for their elements
We had the same experience with the 4:1 baluns on the KT34XA and 40M4 at W6UE. Something on order of twenty years of service with no problems (with the baluns anyway- 40M4 is another story). I should

With regard to the big box stores, I'll second that, John. The last bag I bought from Home Depot was crap. A large percentage of the ties in that bag were so poor that all you had to do was flex them
Paul, This document has a pretty good explanation of how the non-SRTM data was blended to fill in voids: https://lpdaac.usgs.gov/sites/default/files/public/measures/docs/NASA_SRTM_V3.pdf Looks like t

Stan, A couple of questions: 1) Does the counterbore go all the way through the one wall of the outer diameter piece? 2) Is the clearance between the counterbore diameter and the cap screw head diame
