I've received a few requests on how to purchase replacement plugs for the Yaesu G-450A rotor. Use this link: .. http://www.wimo.com/cgi-bin/verteiler.pl?url=yaesu-rotator_e.html The plugs are EXACT Yaesu replacements for the control box and the rotor unit. And, they cost less, as well, and ship quickly. 73, Larry K4AB
