I have an Orion II and a Pixel magnetic loop hooked in as a second antenna.  I 
have been very pleased with the Pixel as a receive only antenna.   On very weak 
signals it allows me to copy the weak signal that I was having problems with on 
my regular antennas.  The Pixel gives a very low noise floor that allows the 
weak signal to be heard.  My regular HF antennas consist of full wave loop for 
160, 80, and 40M and a 204ba 20m beam.  It was worth the money to me.
