Another very good choice for this application is the GLB Preselector / Preamp from Simrex Corp.
I have several of these deployed on 144 / 220 / 440 Amateur repeaters and they all perform very well. They can be tuned to maximize gain or selectivity per your requirements and their support is outstanding. http://www.simrex.com/site/products/special.htm PRESELECTOR PREAMPLIFER a..
