Hi gang,
 
I have acquired a commercial UHF cavity I would like to use on 70cm. The 
coaxial resonators as they are, only tune down to 470 MHz or so. 
 
Would it be practical to use a dielectric within the resonators to lower the VF 
and get the resonant freq down the approximately 9% required?
 
Any thoughts?
 
Thanks in advance.
John, N9RF
