RCI on 9515 seems to be having troubles once again. Throwing a lot of
junk up the 31 meter band this morning. Steve Holland, MI Drake R7, R8 and R8B |

Hi Steve. How did you come up with that ant. on your website. It seems to
work good. Brian -- 73 and good DXing RX: R-5000, SP-600 JX-6, SX-28 Ant: 100' longwire, Evesdropper Dipole Brian's Radio Universe http://webpages.charter.net/brianehill/ "N8KDV" wrote in message ...

The shot is from the end of the 100' wire, before I lengthened it to 200'. They seem to work OK, and this is the type of antenna I've been using since about 1988 or so.

I don't take quizzes! And I only offer the matching transformer on a very
limited basis. Perhaps one a year, probably less.

N8KDV,
If my formatting caused some offence, I apologize. (It was not intended to be a quiz.) What I was seeking was any 'insight' that you have gained by using these two "Low Noise" Random Wire Antennas. Plus any unique directional and/or non-directional properties these two "Low Noise" Random Wire Antennas 'exhibit' over the Frequency Range from 500 kHz to 30 MHz. (Medium Wave to Shortwave) Also, I do not know how to describe these two "Low Noise" Random Wire Antennas. * They are not High UP in the Air. * They are not Laying ON the Ground. * They are actually not NEAR the Ground. I would say that they are best described as an On-the-Fence Antenna: Without the Fence, and if the Fence was a High 9 Ft. Tall Fence.) [TALL CORN] -or- [STEP LADDER HIGH] -or- [ELEPHANT'S EYE] ? Did you try these Antennas at a lower height before settling on 9 Ft ? ? WHY - Nine Feet High ? =R= (My Reply) See additional Comments that are 'inserted' in to the body of your prior Message. iane ~ RHF = = = I Ain't No Elmer (I am simply trying to Learn about SWL Antennas and Share the Knowledge.) .. .. = = = N8KDV = = = wrote in message ...

Also, I'm afraid to point out that the design pre-dates the John Doty concept. (as far as I know). True. There was nothing really new in my design. I wrote up the design because I hadn't seen a good clear explanation of nonresonant wire antennas with effective common mode decoupling. The article has been posted on several web sites and published in several newsletters: people seem to find it helpful. But it doesn't represent an invention, it's just a piece of writing.
