Yeah I understand. I'll probably go with the RH77CA. I was just wondering about the Super-Scan Duck because it says "Three different broad banded resonance points, 100-175Mhz., 402-512Mhz. & 800-950Mhz.. This advance design yields a antenna that displays a Tremendous improvement over original equipment antennas and after market competitors" and I listen to channels in all those bandwidths.
