For some time I have been getting queries regarding a series of TT posts that have been prominently archived on google and contain incorrect information, much of it personally focused on ME. This pos
You guys are feeding on each others' gross speculation--the same way you did it to me when I was on a PBS documentary in December 2010. You were totally wrong then, and I did not appreciate the abuse
Uh oh, there's water/moisture afoot. Not a temp issue. Most likely happening at the connector interface(s) or at the matching system at the antenna feedpoint. Could be the traps, but they'd have to b
I have experienced arcing (dielectric breakdown) on one of these--manufacturer unknown, but assumed PRC origin. This was after 1 year in-line. About 500 watts at the time. I don't know how you avoid
To Whom it May Concern: It is a pleasure to recommend CURRENT BALUN for the position so described. I have known and worked with CURRENT BALUN for more than 40 years and have always found CURRENT BALU
Lyme disease is endemic and epidemic in this part of Massachusetts, mostly because we let Bambi and his ilk run free to be a pest to you and me.Deer are the common vector. Some doctors are paranoid a
Well, I agree that tower and antenna work most certainly takes you into territory that these ticks inhabit--if you live in a Lyme disease area. In part, this because deer hang out on the paths that w
Good points Bob; you are correct that the mice are becoming a much bigger factor--blame the acorns: _http://www.wired.com/wiredscience/2012/03/acorns-mice-lyme/_ (http://www.wired.com/wiredscience/20
Dick, We feel for ya buddy! Its a terrible disease that doctors don't take seriously. Do you do periodic doxycycline regimens? If not ask your doctor about the latest on that. Best to you OM! 73, Chi
In order to circumvent the usual secondary and factually inaccurate comments(to be kind) I have seen in the past, I am posting this link directly. _http://www.southgatearc.org/news/june2012/ham_genui
Yeh, you can get better gain, bandwidth AND lower sidelobes. See 'Optimization of Wire Antennas', Landstorfer and Sacher, Wiley Interscience, 1985. The Innova designs use end-bends to shrink the proj
Sorry Dave; the Moxon phasing is caused by the 1/8 wave separation. It is a close-spaced 2 el Yagi. The Hex is a Moxon with W bendbacks of the driven and parisitic. The virtue of the Moxon is that it
I should add that the 'true' Moxon that you refer to is about 3/8 by 1/8 waves. I am used to the end loaded shorter versions here: 1/4 by 1/8. I have a fractal version that is 1/8 by 1/8 waves. 73, C
About 6% bandwidth for 2:1 SWR, 5 dBi (measured), 25 dB F/B(measured). It uses conformal circuit boards, so I don't expect this will be of any real interest to hams. Light and portable though. I didn
Yep. I am saying you are wrong. I confirm that I am saying that:-) Not a reflection nf you, but the antenna and how it works. 73, Chip W1YW In a message dated 3/20/2013 2:12:40 P.M. Eastern Daylight
It's only 'critical' in the sense that at some point mutual coupling kicks in at the closed-spaced nearfield. Its not a mystery. That's the principle behind metamaterials. A Moxon is a folded two ele
73, Ward N0AX Hi Ward, I certainly could do this for you, as I am retired from BU, where one of my jobs was as a professor of mechanical engineering; I taught the statics and dynamics courses over ma
