[QUOTE="Terryl, post: 1036919, member: 369937"] If your not going to be transmitting on it then it may work, some yagis can cover a bit further out of their designed band on the receive side. You could do a little cutting as the 1090 MHz 1/2 wave is 13.75 centimeters, versa the 900 MHz at 16.65 centimeters. This 2.9 cm difference you would cut off on all elements, (1.45 cm on each end of the front directors and driven element) but leave the back reflector alone, it should work just fine then. [/QUOTE]
