Any sugestions on how to minimize coupling between a 160 m, 5/16 inverted "L", vertical section 72Ft. from a 5/16 (electrical) 80 meter vertical? The vertical section of the 160 "L" runs parallel to the 80 meter vertical and is separated by abt 3 ft. The "L" is not impacted by the 80 meter vertical but the vertical detuned. Tnk Max KH6ZM
