c band

[pmb1010]

find a C band station, if you can - closest to your highest south sat. Use that to dial in your dish alighment roughly.

THen, switch to Ku band and fine tune your LNBF on your dish once you find a signal there.
You'll find the Ku will be more fussy as far as skew and focal length but once you get something C band will fall into place.

My indicator diamond on the C/Ku pointed down (at 6'oclock).

also this dish has no markings on it. like elv. or scales etc. i left all the settings from when it was used last which was right down the road so should that be a good starting point or is it not wise to trust it

to check elevation on the dish use a inclinometer.

Your dish settings with exception of alignment on the pole for true south should be ok providing it was an operational dish at one point with current settings BUT analog C Band is far more forgiving than digital so you may need to tweak it a bit once you get going.

Settings in the receiver are going to depend on what you are doing. If you are setting up a C Band sat then you would use 5150 for the LO. If I am not mistaken the 621 is a standard on the Ku side so for the Ku sats you would set the LO at 10750. I believe the 621 uses 22Khz for switch between the two bands with on for Ku and off for C. You will need to set this accordingly as well. If the lnbf is a 621-2 (I think) it would be UNI for the Ku LO and it uses DiSEqC ports as the switch.

The UNI Ku BSC lnbf is the one I have listed in my signature. Have you checked the holes on the dish? Did it have a single C Band lnb on it or a Corotor II w/ two lnb's? Depending on your location you want to be able to see all the way left and right of your location. This means you would want the actuator extended halfway when pointed at true south. If you are limited in one direction you would offset it as it is easier to push than pull. What this means is as an example if you were at 123 you would not need much west travel so set it up as the actuator would push it's way back to 123 from the east and pull from the west since there would be few sats west of 123 you will get.

If you are blocked by something on one direction (trees, building, etc) same applies.

so i purchased a magnetic angle finder from sadoun but i have no idea how to take the readings or where? i feel like a dope. i am not even sure i can read the chart correctly to find my settings for declination angles and so forth. i am in Lakeland, Florida. my starting point would be AMC5 right? i went to my dish and realized i had no idea how to read this thing!?

just so there is no confusion on my part, the first thumbnail depicts how i adjust my declination correct?

the second thumbnail is my elevation adjustment
correct?

Yes,those are the correct adjustment bolts.

Hi Keeps: Just like Satnut said they are the right adjustments. but you need to move you angle finder on top of the 2" x 3" tupe where the dish pivots on, not on the side shown in picts where the actuator is bolted. set the 2" X 3" tupe to 28 degrees with the treaded rod, with the angle finder, then move the angle finder to the ring that (angle finder will be up side down) that bolts to the dish then adjust you're declination adjustment ( 1st picture) so the angle finder reads 32 degrees. the 32 degrees is adding the offset for you're area to the elevation for you're area. and all this will be done wile the dish is in the bird bath position, with the high end of the 2" x 3" looking to the due north. then start you're tweaking, good luck..

man i guess i have smoked too much of that sticky icky???
i am still completely confused. the angle issue has me at a dead stop.
wejones has been PMing me with solutions but it looks like Greek to me.
can someone tell me what the numbers are that i need to set and how to do it? thanks for answering these questions you have answered a million times before.

Ok Sunshine have you moved anything yet? It was a preset system before it was moved. The first pic shows declination setting. Your second pic is elevation. Put your angle finder on the top of the square tube in the top of the pic. Now remember what way you are going. You may be subtracting 90 from your finder due to direction it is pointed. You want the dish at it's peak position in movement which is when the dish mount brackets are aligned straight with the mount brackets. Clear as mud There is a bracket that is mounted on the rear of the dish that can be removed with the dish from the mount bracket with 2 bolts (pivot points). At the same time but not required at this point ideally your actuator would be halfway extended.

Rainman or someone can chime in with a site that gives specific readings for your location. I do not have it handy. Set your elevation per as well as declination. Now gently move the entire assembly on the pole until you find signal. Once you find signal scan it is and determine what sat it is based on channels received. We will adjust from there.

this is the best site that I know of for setting up a c band dish.

It might help to watch the boresight video from Shaun Kenny.If someone could post a link to it,or try googling, boresightripco.com.and see if that helps.Very helpful video.
