You meant I could use the aluminum window frames as a big antenna?
![]() YES! i have done that and it works great... even better than bedsprings because you can make it vertically polarized by feeding in the right place. Did u solder a wire from the radio to the window frame? How did you do it? -- @~@ Might, Courage, Vision, SINCERITY. / v \ Simplicity is Beauty!

Antennas usually are made of aluminum as copper is somewhat heavier and silver and gold is to expensive. Since lead is now banned in a lot of places especially with solder you can now buy solder that is doped with Bismuth ! Now you can't coat your elements with it but *if you have a solder bath you can run copper wire thru it. The bismuth is brittle but with the underlying copper it is stiff enough to stick it on the antenna elements. I am assuming that the applied current would travel along the bismuth coating instead of the aluminum and therefore should increase gain for antennas that use coupling methods such as the Yagi tho bandwidth may well suffer some what. What do you think? testing, 1, 2, 3... can you hear me now?? |

You guys are just nuts to consider messing around with a device capable of emitting Orgone Radiation! I mean, you may doom yourself to a life of having to use medical marijuana to alleviate the migraine headaches and pain! Not even getting into the heavy genetic damage which is likely to occur!

Your writings and past postings are available for all to see and judge what sort of person you are. You continually embarrase yourself. I invite all to view your past postings to see what manner of man you really are. As for the Peltier effect that you are referring to, it is you who needs to check the facts as to who posted that. It certainly was not I. But if you have the real facts then spit it out to show that you know them and can prove it, until then you are spitting into the wind. So Tom back to you. What are the "real" facts that you wish to point to and be specific with respect to the connecting physics for supporting data? You may have a open physics book at your side when responding so you can read up on diamagnetic, levitation, neutrons etc since it is very clear that you were able to jump semesters at will leaving large holes in your educational standing which does not allow you to debate in a reasonable fashion. OR You can continue with verbal bullying without contribution or follow up discussion with other members of the group. |
