Has anyone else here seen the totally idiotic QST cover for the March issue? If not take a look: http://wirelessestimator.com/articles/2017/cover-girl-climber-shot-could-send-high-schoolers-to-their-
Herb, tell us about the property for the radial field. Is it woods? Is there grass? Is there foot traffic or is it "back 40" land where no one goes? 73 Rob K5UJ ______________________________________
Herb: I admire your drive to do a full ground system. It is really worth it. 1. as many as you can put down as long as possible up to around 120 feet. shorter is okay, just do many many. strap in oth

The Chicago stores were put under partly because hams would use them as show-rooms to look at rigs, then PHONE IN AN ORDER TO AES IN MILWAUKEE to avoid Illinois SALES TAX. Of course IL SKY HIGH Sale
Wilson forget it. These guys are going to take coax to their graves with them. A recent issue of QST could be regarded as the Coax Do or Die issue. There were two or three laughable articles describ
What about buying and cutting and bending threaded rod to make your own? Not sure if the threading and bending will weaken the U though. Rob K5UJ _______________________________________________ _____
CE once told me tube rigs cut plate v. in half to try to quench the arc. s.s. rigs rapidly step down cxr power until low Z ball gap arc gets quenched. arc is vswr event. cxr muting very brief with n
I've heard that you have to be careful sourcing hardware for a tower, especially from a non-tower manufacturer. It has to do with the galvanizing. From what I've been told, the non-tower intended har
this will show you how to do overlapping radials at or below grade http://www.hatdaw.com/papers/groundsystem.pdf 73 rob k5uj _______________________________________________ __________________________
I never fail to be amazed at the contortions coax obsessed hams put themselves through to cling to that kind of feedline no matter what the circumstances are. Rob K5UJ _______________________________
Nothing amazing about balanced line but the people who are inept at how to handle it are amazing. Rob K5UJ _______________________________________________ ____________________________________________
Sadly, it seems little is known about how to handle balanced line outside the vintage radio community. QST doesn't help. The Doctor Is In column does anything and everything it seems, to get hams to
Jim Brown is correct. 160 m. is a medium wave band. HF antenna wisdom does not apply. Of course those in denial will probably never learn; the band is loaded with piss weakers who answer my CQs with

The man asked about RG213. He didn't ask about foam coax, heliax etc. When sourcing genuine RG213 you should pay attention to the specifications regarding the center, shield, dielectric and jacket. T
Typically a series fed inverted L that's 1/8 vertical roughly, and the rest horizontal over an adequate buried ground system will give a feedpoint impedance of around 10 to 15 ohms and a mismatched t
What worked for me were the large barb wire fence staples. Go to a farmers co-op and look for them. At the one I went to they had bins with different sizes, and the largest ones were thick with sharp
When I get home I'll make a point of rushing out to my radial field to let my fence staples know that they've been derelict these past 15 years, not knowing they were supposed to fling themselves out
The term for that is "window line." The line consisting of parallel conductors with spacers is "ladder line." The other design that sounds like what N6RK uses, in which the line is spaced apart by t
