Home Made Coat Hanger Discone

Reddit user soooooil has posted a series of images showing his home made Discone antenna made out of wire coat hangers and designed for a minimum frequency of 130MHz. His thread discussing the Discone is here.

A Discone is a good general antenna for the rtl-sdr as they are extremely wideband, and can be expected to be useful over almost the entire frequency range that is tuneable by the the rtl-sdr.

Another page on a home made Discone also designed for a minimum of 130MHz is here with some brief instructions links to design calculators.

    Wow, just look at all those shorted turns! I wonder why commercial discones don’t have the circular wire tying together the ends of all the radials? Hmmm….

      Cheaper, easier for anyone to construct, less weight, and much easier to disassemble for shipping.
      But mainly because it doesnt make a noticeable difference in performance.
      The ideal discone would be a solid sheet metal disc and cone, but its not worth the trouble.

    I enjoy high-end wideband and broadband antennas every morning with my breakfast soup. My favorite antenna is the raspberry oats discone.
