A Top Band 1/4 wave vertical?

In message , Oregonian Haruspex writes How about a tethered helium balloon instead? This way you don't have to worry about powering the thing. Bell wire will handle 100 watts all day without turning into smoke. Many amateurs would give their right arm for a functioning helium balloon. It's the sort of thing that most LF band aficionados can only dream about. It's a lot easier to obtain electricity than helium. Weather balloons can be found for sale all over the web, and in all sizes and skin thicknesses. They work quite well for hoisting a wire. I tried it one time with two NWS balloons (about 3 feet in diameter, IIRC); the only problem was they bounced against each other constantly. Next time I would arrange them so that one is above the other. A tank of helium isn't overly expensive, either. -- ================== Remove the "x" from my email address Jerry, AI0K ================== |
