[QUOTE="canofan, post: 565454, member: 259756"] I never used an OMT to combine two single band LNBs and kept wondering about the real insertion loss. Browsing through SMWs, I was comparing the specs of the Quattro type E, LO 9.75/10.6 GHz, with the WDL type E, 9.75/10.6, GHz. The Quattro is actually composed of two WDL type E, 9.75/10.6 GHz through an SMW OMT 30. The Spec for the WDL type E, 9.75/10.6, GHz claims a 0.8db.NF. The spec for the Quattro type E, LO 9.75/10.6 GHz claims a 0.9db NF. Simple arithmetic yields the insertion loss of the OMT 30 at 0.1db. Please comments. [/QUOTE]
