> How do people waterproof their 23cms feeds? I want to keep moisture and insects out. I have plenty of insects here! Also I would like to prevent condensation. My latest preamp boxes have a resistor on a metal plate and that works well in conjunction with a pressure equalising system. Ideally what I want is an RF transparent, breathable and waterproof membrane. Does such a material exist? I suppose that it will be sufficient to just cover the WG and not the scalar ring. I have opted for an SM6FHZ septum feed.
