Great ! I was sitting here making my FTA shopping list when that question came to mind so thanks for the answers. In a year or two we'll be upgrading the Tv so I'll be a lot more up to speed on all this. So back to the lnb question is one easier to install/fine tune than the other,has anyone found one to preform better or should I just get the one I get the best price on?
I keep at least 3 10-footers running here an some times more, an on all 3 have 3 different feed set ups, an will try to give you the pros an cons of them.
BSC-621> on a 10-foot Channel Master (just like you got) works very well for C-band, but signals are down a bit on the ku-band, but by far the cheepest to buy, an any lnb-f takes more time to set up, also the 621 is a noisey when I put it on the spectrum aniz, not the cleanest lnb-f in any way but you get with what you pay for. now the down side of any lnb-f or dual ortho feed is AMC-1 ku their polarization is off a few degrees an will notice it when you look at that bird.
Chapperal Co-Rotor wide band feed, on a 10 1/2 Micro-dine commercal glass dish, by far this is my favorite, an the easyest to set up. but it has a servo motor an most FTA receiver won't work a servo, so you need a receiver to the dish an servo (I use a DSR-922) but you can alway use a better grade lnbs (Norsat 8515 c-band & .5 Galant 100khz ku-lnb). by far this is the best for signal going, but that dish has alot of gain buit in it. an with a servo controled feed when you do view AMC-1 you can offset the skew to make up for their shift. Now the down side of working a co-rotor you have to go back an fort on you're tv inputs to change satellites an make sure that you are on the right satellite for you're FTA to get signal, an also the cost of the feed plus the lnbs.
Dual band ortho feed (Chapperal Bullseye) on a 10-foot Channel Master (just like you'res) now this is the best way to work with a FTA receiver, but it gets costley for the feed then 4 lnbs, (have California Amplifer 17 degree w/running SN# for C-band, an Norsat 4508a w/running SN# for the ku-band), now you will need a switcher an a power inserter also, you can use a DTV 4X8 powered switcher will work great. but you can wrap up some money in just the feed an lnbs fast. this is by far great signal for C & Ku both, far better than the BSC-621 could ever do. now with a ortho feed you still have a poor signal on AMC-1 ku but it will be watchable, now a ortho feed is not for every one they take a little more time to set up an get right, but work C & Ku with a FTA receiver its about the best in my book.
Now Kzinbastet on all my dishes I use that channel master scalar ring with the 3 1/4 bolts that holds the feed, to center the feed throat in all my dishes here, an that was 1 of Channel Master great designs that they had. an if you need a comparison of signal quality from the 621 to the ortho, can give them to you, would not be fair to compare with the Co-rotor due to the gain of the dish it is on. hope all helps you to make you're shopping list up, an all the best to you an you're family, an getting you're dish up an running.
