Electric screwdriver antenna tuning

I just realized that we’d never covered the classic amateur radio antenna hack – known as the mobile electric screwdriver antenna. I was looking for a decent writeup, and ran across this interesting tunable indoor antenna. [W2BRI] put together a 5 foot cube loop antenna built from copper pipe. The tuning mechanism uses an electric screwdriver to tune his giant PC Board tuning capacitor. Looks like a nice solution if you’re into radio and have pesky neighbors.

Very nice work.
