[Elecraft] K3 receiver noise figure with KRX3 option

I want to parallel the receivers on my recently-acquired K2 with my K3. I have the KXV3A RX ANT option on my K3 and K160RX option on my K2. The obvious way to couple the two is with a 3dB hybrid but that will cost me 3dB degradation in noise figure on both receivers. The KRX3 option in the K3

The obvious way to couple the two is with a 3dB hybrid but that will cost me 3dB degradation in noise figure on both receivers. Yes, that's correct. However, in general one does not care so much about the noise figure of the receivers since the antenna noise is significantly higher than the
