I'm aware that the PL-259 has loss but what I'd
like to find out is how much loss at 146 & 450 mHz?

Anyone know?

It depends on a whole lot of factors, not least of which is the quality of the
connector and how accurately it is assembled. For 70cm, losses are typically
around 0.7 - 0.8 dB. This might not seen like a lot until the number of
connectors is added up.A base station with a main co-ax run, a socket
terminated antenna, and 2 co-ax tails has 4 connections. That adds up to 3dB,
or half your signal lost before you even look at the co-ax losses. By
comparasion, a quality N-type is less than 0.1dB.
