It’s a problem I’ve often experienced, living 50–60 miles between two big cities my whole life. Wind and clouds definitely have an impact, and even my position relative to the radio’s location. In the car, if I get static, I can inch forward a bit and improve my reception, so metal and wires can obstruct the signal, as well. There are antenna boosters – or at least there used to be. Nowadays, most stations stream their content over the internet, so that might be a better workaround for you.
