In 1979 Mike Lamb, N7ML, founder of AEA once published a brief by Don Reynolds entitled 'Facts About Proper VHF Vertical Antenna Design' which describes the "Isopole" design in detail. If I recall correctly the design falls under patent # 4352109 (viewable at the U.S. Patent website). Later this week I will try to scan the published brief and send the images to Mike, perhaps he can assemble them into a folder or .pdf on the RB website. Both the patent and the brief describe the design in detail and I hope they answer your questions. Oh, the Isopole was only offered in 2m, 220Mhz, and 440Mhz as well as a few commercial bands. Gary
