The van gets better reception! Dunno whether this is relevant here -- but amplified antennas for shortwave I mean HF excuuuse me I mean World Band (tm) reception have always been a bit problematic. In fact $1500-class (cheap or expensive depending on where you're looking from) HF receivers try to avoid amplifying the signal at all in the RF stage, because it's hard and expensive to avoid introducing noise and other undesirable stuff. They'd rather work with the signal at microvolt levels. But amplified HF antennas do work well in some circumstances. The major exception is anywhere there are powerful transmitters nearby, as the amplifiers become swamped with the undesired powerful signals. Someone more knowledgeable may be able to say more specifically about amplified FM-broadcast antennas. david
