Elevation-declination

[MXFTA-FAN]

Need help on this, checking on the other site (ftatalk), found table about latitud-elevation-declination, for my location is:
lat=26
Elev=64
Decl=4.37
The sat close to my south is 99, and checking on dishpointer, my elevation for this sat is 59.5, reading on some other pages about c-band installation, the declination must be subtracted from elevation (64-4.37=59.63) which is close to dishpointer info, am I right or totally wrong? any suggestion is well accepted. So one of the question is the elevation must be set at 59.5 and then add the 4.37 decl.deg. And other question is about the lnb skew, the screws appears to be stuck on the feedhorn, maybe i need to drill the old screws and put a new ones for proper skew, i forgot to take some images of it prior to bud disassembly , and the feedhorn doesn't have any mark to know where is the 0 deg skew.

This is with the declination angle, sorry if i'm not reply quickly.

Need to get one of those angle finders myself. Do the angles from the dish pointing sites coincide with using a 10' C Band dish or are there other considerations to be taken into account?

You should be able to forget about the declination angle as that should have been set by the first owner that would or should have had the BUD professionally installed, the declination is only adjusted if the dish doesn't track the sats correctly like if it hits the sats on the outside ends of the arc but is below or above the sats in the middle of the arc to the south of you, you adjust declination to fix that type of problem but not for setting up the basic elevation.

On my BUD I started by making sure both the pole attach mount was pointed true south (use a compass if you need to do so) and I used the dish mover to move the dish pointing perfectly south so they were aligned and pointed south, you want to do so that when you reach the elevation called for by your location that the dish will be at the absolute top of its arc.

If the pole mount is not true south and is off slightly to the east or west it can throw off the dish arc enough that it will being doing one of these two below when the dish mover swings the dish along the arc, hitting one part of the arc but missing the rest -

Once the pole mount and dish are aligned pointing south and locked down then place the angle indicator on the top of the dish attach ring so it shows actual dish elevation, it should be sitting so that if the dish was level (parralel) with the flat level ground that the indicator would read 0. Then as you raise the dish up you will see the angle indication will increase 10, 20, 30, 40, etc degrees and you keep going until you reach the maximum dish elevation angle for your location as determined by the calculator then lock the elevation adjustment.

Sorry if that was confusing but its probably the best I can do in laymans terms. LOL


Here is a page link for a good site, scroll about half the way down the page. - .geo-orbit.org/sizepgs/tuningp4.html#anchor801578

Further down the page on that link it explains the why and when's on using and adjusting declination angle for fixing satellite tracking issues.

Thats a very good site with a lot of pages of information on BUD installation and setup.

I never checked dish pointer when I set up both my C Band dishes. I figured the AZ/EL would be easier set when the LNBF was on there. I have a sat finder that makes a low pitch noise when near a sat & as you move the dish it get's higher, if getting closer, lower if going farther

Once I got the dish pretty good (side to side) I then worked on the elevation. When that was done. The LNBF had to be adjusted in & out & rotated.

I'm not sure if your LNB will work (Just by looking at the photos).

It looks to be a Analog LNB (Do you have the model numbers?)

The only Analog on that sat is the:
Shepherd's Chapel 4020 V
(Fox feeds) 4060 V

Yes I have that site bookmarked, have yet to really read it. Not quite there yet, still working on other stuff and it is snowing out today. Catching the edge of a blizzard I guess. Still researching parts and cleaning up an actuator. Have yet to get the analog lnb up and order a new lnbf. Have yet to run the cable, want to keep it at the base til I get it aligned. Ya, lots of stuff to do til all the ducks are in a row. And, I still have to watch TV!

Happy Testing and thanks for all the support!!!!

Catthepatch You can find it at your local lowes/homedepot, thats where i buy mine (8.96). All the readings on the pictures are wrong, but i dont knew it, until somebody told me that need to subtract my elevation from 90, so im like 30 degrees off.

Bowhunters im new on this hobbie, so the day when the BUD was disassembled every nut and bolt in front of my was removed and no picture of the original position of lnb, elevation and declination. Thanks for the info.

Augoldfinger i dont have a satfinder, but i could use the tone of my cs6100 i think is better than the pansat3500-CS8100.

You bet a CS6100 works great as a sat finder. I have one & have used it several times

What about the model number Gold, its an analog lnb, or it may work for digital signals. And what do you think about the "new & improved" DMX741 C/Ku listed on sadoun site, just in case the actual lnb wont work.

I'm sorry my friend I just don't know anything about analog. I do have a DMX741U & a DMX741 & I like them both very much.

The DMX741U actually preforms a little better, but this is not 4DTV capable, & it does not do well on AMC 4 at 101, & AMC 21 at 125. I do like the standard DMX741 & use it now as my main LNBF.

I think that these two LNBF's are equal on the C Band side & have not noticed any difference...Only Ku.

Thanks Augoldfinger good to hear that you have both tested, i'm going to buy the standard lnbf fta compatible. By the way the "U" on the other model is for universal, because my pansat 3500 works very well with universal lnb (Ku) , find lot of feeds during blindscan.
