Re: Potting ADS-B LNA

Usually to mitigate condensation you don't make the box airtight. You get a waterproof box, and drill a hole in the bottom. Then connect it to a short straw like pipe, or provide an additional non-airtight rain cover. Also cover the circuit with conformal coating spray to reduce the risk of condensa...

Re: Ceiling Fan AGC?
