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.
