1. As such systems were introduced into service, lobe switching generally disappeared. 2. "W�rzburg C " featured lobe switching to improve aiming accuracy. 3. Lobe switching offered greatly improved accuracy for the addition of a small amount of complexity.4. Had lobe switching to improve accuracy. 5. Major James C . Moore was assigned to head the complex electrical and mechanical design of lobe switching antennas. 6. This enabled the system in effect to switch from the rather broad " scanning for maxima " to narrow lobe switching . 7. Each pair of antennas was connected to a motorized switch that rapidly switched between the pairs, a technique known as lobe switching . 8. Even with the relatively long wavelengths used, accuracies on the order of ?a degree could be attained with these lobe switching systems. 9. The wide-band regenerative receiver used Acorn tubes from RCA, and the receiving antenna had three pairs of dipoles and incorporated lobe switching . 10. The wide-band regenerative circuit used Acorn triodes from RCA, and the receiving antenna had three pairs of dipoles and incorporated lobe switching .
