RCI 9515
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 ...

Brian Nothing much to the antennas, they are simply 70' and a 200' wires mounted about 9' above the ground. I use matching transformers into coax, and the coax is buried, then heading into the house. 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 plan on putting up a inverted vee for at least the 60 meter band this coming summer.

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 ? ?

We do have a site up about 100 miles from here with 6 antennas, ranging from about 350' to 700', spread about the compass. All of them with matching transformers, and the coax buried.

I try to get as much wire up as I can and I usully run one North & South and the other East and West. Right now I got enough room to run 100' longwire N&S and the Evesdropper is East and West. It works ok.
