its true there was a starduster m800 i owned one years ago,
i sold it to an old guy who used it for years, this old guy was an instrument technition at the loacl power station and a real MARCONI type character with a large chart on his shack wall of all the different antennas he owned with vswr bandwidth and singal reports for each antenna, half the antennas he owned originally belonged to me,
last year he gave me a call and asked if i wanted it back as he was having a clearout and always said if he was getting rid of either that or my old sigma4 i could have them back,
when i picked it up we had a chat about it and he told me that inside the fiberglass tubes around which the coils are formed are small capacitors forming a parallel tuned circuit one of which he had to replace as it went short and altered the tuning,
the shortened radiator had a large loop which was as the old guy said bifilar wound ( one turn clockwise then up about 1.5" and then one turn anticlockwise )
he claimed that cancelled the radiation from the loop,
he also said it was a clever way to make the most of the usa height restriction on cb antennas in the same vein as the astroplane but using a different method of achieving a similar goal of raising the point of maximum radiation,
i took pics to post here and gave the antenna to a ham friend because it was in too poor a state for me to be bothered with, it only had sentimental value to me and my buddy wanted it,
i lost the pics
,
come on jack what did that loop do on the old m800 and why parallel tuned circuits in the 3 legs?
