The M5 should have a narrower beam width so it sees less (has a smaller aperture). Once you're pointed to a station, the M5 should sound quieter, but give higher signal to noise. You might not see that on the needle though, but you should be able to hear it.

If the noise floor is the same or louder on the M5, then there is a problem. Could be something else in the system or the antenna.

Same thing with telescopes, when you crank up the magnification, the objects get dimmer (not as loud).
