I just passed my tech test and wanting to try some SOTA with 5w HT (2m/70cm). I ordered a Slim Jim Antenna but am a bit confused about what works best masts. I read that carbon fiber is conductive so may effect antenna. Fiberglass poles and such seem rather rare nowadays. I’m thinking that a PVC may work reasonably well to make a 6’ mast that attaches to my backpack? Any other thoughts, suggestion?
