The distance is not as important as providing two paths of differing L 
through the VHF suppressor in order to provide a low Q at the anode's 
parasite frequency.  note - Low-Q is good in a VHF suppressor because 
it reduces VHF amplification,
-  Do you have a dipmeter?

Indeed, Bill, but the real test is near the end of a contest -- 
especially after the local electronic parts emporium closes for the 
weekend
