[amsat-bb] GAAS FET Preamp Component Question

I'm planning to build the GAAS FET Preamp for 430 MHZ that's in the 2008 ARRL Handbook on page 14.37. One of the components on the drain of Q1 looks like a ferrite bead. I've never used these in construction before and the parts list doesn't specify any particular value or rating. Does anyone know what value/rating should be used? Any info would be greatly appreciated.

Thanks, Gene (KB3ONA)
