Hi,

I have an interesting project! I am using a RF receiver device which has a
50 Ohm RF input. I want to use a PCB printed antenna on FR4 board, not
unusual you say. but I need to pot the whole PCB in resin to make it
waterproof. The receiver only needs to work when floating on water! Has
anyone any experience in PCB antenna who would be so kind to comment on the
effects, and possible actions to counter any effects, of the potting. The
resin is much like araldite.



Any thoughts much appreciated.



Will
