SteppIR Antennas E - 3E Hgh Wnd Kt SteppIR - Why Compromse? The SteppIR antenna was orgnally conceved to solve the problem of coverng the sx ham bands (m, 17m, 1m, 1m, 1m and 6m) on one tower wthout the performance sacrfces caused by nteracton between all of the requred antennas. Yags are avalable that cover meters through 1 meters by usng nterlaced elements or traps or log perodc technques, but do so at the expense of sgnfcant performance reducton n gan and front to back ratos. Wth the addton of the WARC bands on 17m and 1m, the use of nterlaced elements and traps has clearly been an exercse n dmnshng returns. Obvously, an antenna that s precsely adjustable n length whle n the ar would solve the frequency problem, and n addton would have vastly mproved performance over exstng fxed length yags. The ablty to tune the antenna to a specfc frequency, wthout regard for bandwdth, results n excellent gan and front to back at every frequency. The SteppIR desgn was made possble by the convergence of determnaton and hgh tech materals. The avalablty of new lghtweght glass fber compostes, Teflon blended thermoplastcs, hgh conductvty copper-beryllum and extremely relable stepper motors has allowed the SteppIR to be a commercally feasble product. The current and future SteppIR products should produce the most potent sngle tower antenna systems ever seen n Amateur Rado!
