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.
