Never had an antenna on 30 meters and the new little tower I am erecting 74' has as Skyhawk triband antenna @ 75' I though I have this old F-12 rotating Dipole EF401 ??? not sure of the # But Why not a rotating 30 meter dipole 8 ft above the Triband Antenna. So....... has anybody modified a F-12 40 meter dipole to 30 meters ? Wayne W3EA
