The two units that I originally purchased from sctv in SoCal back in '98 had the
plastic/metalized shield in place and at that time it was decided that it was
not necessary to keep it in there after doing the IF and hairpin mods and I
didn't notice any appreciable difference with a tracking generator at work
though my setup to test it was crude ,but it had no effect on gain , though it
may be to isloate the unit from radiating its own lo , but if you see most
pictures that show any mod's show the shield out ......

my two pennies worth 

now if I could just get my antenna up high enough and aimed so I could be lucky
enough to hear AO-40 :^P   ( no rotor up to point with yet )
