The signal (including received noise) from the antenna is reduced by 3 
dB when sharing.  If you can still hear band noise from the antenna, you 
are only losing 3 dB overall gain, not S/N.

If AGC is activated, it is reducing gain so the splitter loss is 
inconsequential.

Only if the band is so quiet that you don't hear band noise when you 
connect the antenna do you risk degrading S/N by up to 3 dB.
