      Slightly off-topic, but there is another very interesting small RX
      antenna - The W2PM Mini Diamond Receiving Flag

      http://www.ok1rr com/e107_ plugins/content/ content.php? content.76

      In contrary to the mini K9AY preliminary study it is proven design which
      works. My ~15 dB 2x 2N5109 preamp plus the internal preamp in my Orion
      were not the best but it does listen... The main advantage is that this
      antenna is ground-independent and can be built as rotatable.
