Although you need to add capacitance to get it to tune, many antenna tumers have too … WebA half wave dipole for 20m should be a full wave dipole for 10m, so it should at the very least receive well on 10m. But again--listening to SDRs in my area, I currently hear a lot on 10m. But on my radio--practically nothing. (On 10m, I do occasionally hear some very faint beacons or something, but otherwise nothing.) Thanks for any ideas!
