Speaking of 6 meter conversions, I have received (2 ) 4 can pass
reject 300 khz duplexers for 72-76 mhz. My thoughts are to cut them
in half and lengthen them about a foot..My question is how important
would it be if the new addition section was copper but was not silver
plated inside, as the wipe portion of the can is lower where the
silver plating will still be...Will this disruption in surface
conductivity be an issue????? It looks like the silver plating add on
could be done but will add significantly to the cost of the
project...I was planning on adding copper sheet rolled to fit,
riveted and silver soldered......and welding a splice into the tuning
rod.. I think they are Celwave products and the tube is already made
of what looks like rolled copper sheeting... ( about as thin as
heating ductwork) fairly easy to dent... unfortunately.....:-)
Anyone "been there done that" ???
