Over the years I have seen many base antennas. When I first started talking on the radio, like maybe 30 years ago, possibly 35 ( I know Jimmy Carter was just elected President). But anyway, I always liked the Sigma 5/8 wave groundplane, because that's what my father had hooked up to his station, I was amazed when he talked to my Uncle who lives in Australia on 26915, back then he ran a 10 tube D&A Phantom. When I got older and more into the hobby the Sigma had started seeing major rusting and the top aerial had bent after hurricane season which was bad, so I had to find my own antenna of choice and wanted another Sigma, but was struck down when I found out Sigma went out of business and was told the closest thing I could get would be an Alpha 5/8 antenna so I ran that with the same old D&A 10 tuber. After reading all that I guess you can see I always loved the Sigma 5/8 wave. 73's
