. QST . No Switching! No Stacldng! Ho Adjusting! The Tri-Bander is a compensated typebeam with four elements mounted on one15 boom. Two elements function for 20meter operation and the other two for 15and 40 meter. Because the latter twobands are not in direct harmonic relation,the beam operates at somewhat reducedefficiency at 21 mcs. but gives maximumperformance at 7 mcs. and 14 mcs. For-ward gain on these bands is 5 db. andfront-to-back is 20 db. SWR is atresonant fretiuencies. The Tri-Banderis complete with coils, Auto-LectronicCoupling Yoke and all necessary hard-ware.
