I have channel 8 and channel 10 VHF locals in my area. I use a Channel Plus
DA-500A preamp in my system. It was recommended by a VHF guru as a high-power
preamp that is more overload immune. I have a K1UFH 144.200 notch ahead of it
to keep my APRS digi out, and had to throw a  coulple of FM traps on the input
still, to keep out herringbone from strong local FM stations (back in analog
days), but it was still much better than the cheapo consumer stuff even without
the extra filters.
