Try Webster Communications in Rochester, Michigan. This is the old Webster Band Spanner mobile antennas. He's still around, I saw him at Dayton this year. He sells Bird elements.
Also, don't forget Coaxial Dynamics that sells a wattmeter that uses elements that are compatible with Bird wattmeters. 73, Gerry, K8GT _______________________________________________ UR RST IS ... ... ..9 QSB QSB - hw? BK
