[TenTec] Omni6+ roofing filter

[Clark Savage Turner]

INRAD did some experiments with a narrower roofing filter in the OMNI VI 
and the improvements were not large.  The OMNI VI has such a solid front 
end that the roofing filter is apparently not a big deal.  You can call 
George up at INRAD and ask about it, he is usually happy to discuss his 
thoughts.
