Yeah...I have a new 8115 coming! I hope this helps me lock some harder to get s2 feeds!![]()
I hope you have better luck than I did. I upgraded from my OLD Cal Amp (I think) lnb that had a freq stability somewhere in the 750-1000 KHz range, to an 8115 a year or so ago, with the same intent. I thought that the better freq stability (I forget exactly, but I think the 8115 is around 100-150 KHz). Well, despite the fact that it was a much more stable lnb, I couldn't lock a lot of transponders that I WAS able to lock with the old Cal Amp. I think it's because the old LNB had a bit more gain, and the Norsat must get it's freq stability at the expense of a bit of gain.
I took a peek at the Cal Amp specs. The 140105-1 is DRO like the Norsat 8115 with a poorer frequency stability (500 vs. 100 KHz), but much better phase noise specs (-73 vs. -65 dBc/Hz @ 1kHz, -95 vs. -80 @ 10 kHz and -110 vs. -95 @ 100 kHz). One might question some LNB suppliers over specs, but these are both reputable manufacturers and the differences are not small. I'd have to do some math to see whether this would improve 'lockability', but it sounds interesting. Are there any good Cal Amp suppliers?

I bought Cal amps from here before:
Vincor Limited - Earth Station Antenna and Satellite Communication Product Specialists
Installed my 8115 today. Its rainy and stormy here today so my observations could be flawed.
My 91w c band signals went up a little, while most signals across the arc are unchanged.
The one thing i do notice is the signal quality is very smooth and not jumping up and down on most transponders. So i guess my little cheap dmsi bsc 211 13 degree lnb was not terribly bad using norsat as a reference.
S2 is about the same.
I've been "eyeballing" this LNB, also, since my much older, "standard freq stability", Norsat doesn't lock the S2 stuff. (I'm too lazy to go out in the rain to check the model number). I'd be really interested in hearing how it performs for you.
