LOL Incidentally, one of the tricks I learned (the hard way) was to replace the mobile whip antenna with a piece of copper electrical wire. Then cut it to length, tune, optimize, test and whatever. Once the optimum length is established, replace the copper wire antenna with the real stainless whip, cut to the exact same length. You have wine? Why didn't you say so, that changes everything: The antenna transfer function of wine is highly exponential and very non-linear. A little wine will produce a superior antenna. However, incremental increases in wine dosage will tend to have lesser effects. At some threshold, additional can cause a substantial drop in performance. It may even go negative. Think equilibrium. Or, to summarize, the more complex the antenna, the more meters you are going to need ... LOL Kinda reminds me of a former tech. All day, he would spend his time working with the latest state of the art test equipment in the lab. After hours, he would drag out his ham radio, and tune the xmitter to maximum using a light bulb dummy load. Attempts to convince him that the company test equipment might be useful for dealing with his radios were futile. If away from my laptop, the programmable calculator is always in my pocket! (I mean, my gawd man, I have space invaders on it!) straight-face That doesn't leave much room for the pocket protector. I collect HP calculators. There are numerous calculators scattered around the office and house. No need to drag a calculator around. ... some patents are NOT what they used to be ... but then, there has always been some suspicion about the politics involved, not to mention courts ... There's plenty wrong with patents that I don't wanna get into. Suffice to say that it's very helpful to understand something about patents before trying to create one. I'm just suggesting that you make the effort to read patents. Groan. I decide to stay home today to recover from my home cooking. Outside, PG&E (the power company) and the local tree service just arrived.

I had neutralised the weak force such that particles could arrive but not depart! Yes it was an error on my part but it didn't rule out the value of experimentationj. Has anybody got a use for such an antenna?. This error in many ways provided proof that the trail I followed was coirrect. This is why I have delayed the sending of a antenna to AC6XG as the correction took over some of my free time. But Jim understands what happened not necessarily why. as he does have trust and an open mind as well as my respect. When I supplied an antenna to the U of I I gave them a sample of the same antenna in Australia because of their treatment towards me and comments made in advance of getting the antenna. Thus I gave them exactly what they expected to get based on pre examine comments similar to those of this group He who laughs last laughs longer and forever. Something like getting a bunch of wire with lip stick all over it Best regards Art Unwin....KB9MZ.......xg |

Now that is worth a nobel prize! publish that and get it peer reviewed in a respectable physics journal and i will personally nominate you for a nobel! |
