Our AA7C has been a favorite for the serious DX'ers, and now it's even better! It works on all bands - shortwave, HF, VHF and UHF! Imagine a self-contained unit just 4 inches square that pulls in the signals like a 60 foot long wire; that's the advantage of an active antenna! For jazzing up VHF/UHF receivers and scanners the AA7C has you covered too. Over 15 dB of gain pulls in the weak ones whether you use the included telescopic whip or an outside antenna. Unlike it's predecessor, the AA7C requires no band switching to cover the range of 1MHz to 800MHz. That's right, it has a bandwidth of 800Mhz with up to 20 dB of gain at an input signal level up to -20dBm. A pair of N-Channel MOSFET tetrode transistors provide the gain. Because they are tetrode MOSFET devices, the gain adjustment is accomplished using a variable DC control voltage so the gain control potentiometer won't cause any noise if it gets "dirty."
