Here's a pointer to the Directive Systems web page for the 3347LY.
   http://www.directivesystems.com/3347LY.htm
On that page is another pointer to a PDF file with the owner's manual.
   http://www.directivesystems.com/PDF/3347LYK.PDF

The elements on that model range in circumference from 10.883 inches to 
13.931 inches, so the corresponding loop diameters would be 3.464 to 
4.434 inches.

For comparison, the 1296 MHz model (2355LK) manual is at
   http://www.directivesystems.com/PDF/2355LYK.PDF

The loops for 1296 MHz range in circumference from 7.540 to 9.794 
inches, or diameters of 2.400 to 3.118 inches.  That should be a 
difference that is easy enough to distinguish so that you can tell which 
band it is for.

Bill (K0AWU) has 1296 MHz, but not 902 MHz.  Hopefully, someone else up 
your way will chime in.  I don't know how far W0GHZ has worked on 902 
without propagation enhancement, but I think that if anyone here in town 
would be workable, he would be the guy among the locals here.

73 and good luck!
