> Hi All,
>> Well, if you are going to get fancy, you might try the Moxon rectangle for
> 40. It really is a two element beam, with the ends folded back. We built

> dipole or inverted V, it has a lower angle of radiation. We hoisted it up
> as high as we could get it from a 37' tower and 35' ladder. It drooped a
> bit, but was at about 30'. Did real well. From SE New England, it covers

for
