[QUOTE="canofan, post: 500942, member: 259756"] Very nice, thank you. Pardon me if I am trying to plck your brain. But I want to get back to reevaluating the Invacom Quad QPF31. _www.satellites.co.uk/satellite/archive/t-113826.html _http://www.invacom.com/products/qpf_031.htm _http://www.invacom.com/products/documents/2ndgenQuadpolardatasheetwhite.pdf This has 4 outputs 2 of which concern us for Nilesat. With its 0.3db noise figure. and its two bands 11.7 to 12.2 and 12.2 to 12.7 voltage switchable for polarity and 22khz switchable for band selection. Qualitatively we know that the switching circuits introduce insertion loss. Quantitavely how much insertion loss do they introduce? Do the losses offset the 0.3 db advantage so that they become less interesting than the Norsat? [/QUOTE]
