I think we've beaten Grounding into the ground enough for this thread
I'd now like some opinions on how to fine tune the Dish once you got a signal
Well, here's what I did:
Once I got the signal strength as high as I could on 299 and my skew was set properly and my receiver was authorized, I abandoned the signal strength meter altogether.
With the receiver still on 299, select: Options 6-4-7. After a few seconds some numbers will appear at the end of Line C on that screen. The left-most number is the signal strength
, and the right-most number is the signal quality
(the EcbNo). The EcbNo should be formatted like this: +8.2. The idea is to get the EcbNo number as high as possible, without further regard to the signal strength. With all clamps tight on the dish, apply light pressure left, right, up, and down. Note how each of these motions affects the EcbNo. If you see that movement in a given direction increases the number, then loosen the appropriate clamp enough to actually tweak (and I mean tweak
) the dish, re-tighten the clamps, and repeat the procedure. Before going too far with this, change the channel to a F2 channel such as 350 or 700 and try the same thing. Note that this operation can be very sensitive....even the final turn of the wrench in tightening a clamp can have an effect on the EcbNo.
When tuned to a SDef channel, an EcbNo of +8.0 or above is "good", but in Canada you may be able to do much better, say +10.0 or even higher. From this point forward, it's a question of (1) finding the optimum EcbNo for both satellites by repeating the above procedure back and forth for a channel on each satellite, and (2) how much patience you have. Sooner or later you are likely to find that improving the EcbNo on an F1R channel will decrease it on an F2 channel. Personally, I got EcbNo's from both satellites of about +8.0 (in Arizona) and called it good.
Now if you're an HDef person (and I have no experience with HDef) I've read that you will find the EcbNo's on HDef channels will be lower than SDef by about 2.0. So if you're getting +9.0 on SDef channels, expect +7.0 on HDef. Perhaps someone else will confirm, but if you are an HDef person, perhaps it's best to use the HDef channels on each satellite to maximize the EcbNo.
Note that the EcbNo's will fluctuate from moment to moment and will not be the same on all channels from a given satellite. While I don't think the EcbNo will have an impact on the quality of the picture, it will have an impact on how long you will continue hold lock on the satellite when the weather gets bad. The higher the number, the more rain/snow it can stand.
Good luck....sounds like you're getting there!
