Put a large dist on the bottom of the tuning rod. make sure the diameter is such that you have no less than a 1/4 inch to the wall of the can. then put them on the network analyzer and tune and trim the disk as needed.

They have 2 notch threaded rod stubs on each can. I was amazed to see how close spaced they were on the freq's in them. I did find some information on home plating but looks like the better part of $500.00 for a kit to do it... and a bit of a learning curve.. Anyone here done any home silver plating either???? That insight would be useful too! I am more interested in if it is necessary? Doug KD8B At 09:56 AM 4/28/2006, you wrote: >Doug, >I have a set of the same Wacom cans you referenced.
