This performs pretty much as the datasheet that Nooelec publish. Gain is high, and the passband follows what they say. It's very sharp on the lower side, providing strong attenuation to airband and FM broadcast, but rolls off more gently on the other side, still allowing some of the very strong 153MHz pager signals through.
Realistically, I'm not sure the LNA is needed. I get reasonable signal strength for NOAA satellites with just a V-dipole. The high gain means I'm brining up the noise as well as signal, and it's overwhelming rtlsdr dongles. Just a filter might work better for me, but your mileage may vary.
