[BC] Question for Richard

[Mike McCarthy]

The best way to do this is to take the reciprocal of the velocity factor 
and multiply by 984 or 300...which ever metric you happen to use for full 
wave length.  492 is 1/2 wave in free space.

IE...for a velocity of 89%, take 300 (meters) x 1.1236 for a compensated 
length.
