iv herd of them antennas but iv never seen one. online or in person. and if i remember right. i dont think anybody that talkes on our local channel down here run one either. but i do kno that one of the locals run a se of moonraker 4's. (i think thats how you spell it) and they are nice and talk and receive amazingly! i asked him where i could find a set back when i lived in a place that i had room to have a set, and he said they where discontinued. :'( i was pretty sad when he told me that.
Oh don't be sad. The Moonraker is one darn good antenna that everyone's heard of, but it still won't keep up with a well tuned 4 element quad.
