Have had this satellite kicking around for years, got to be at least 25-years old or more. an it was made by Northern Satellite Corp. an model is NSC12-1 ( all raised letters in back of dish top left of center). an had it from time to time on setting it on a Sats for a feed that I could not lock with other dishes that I have here, an it became a pain to move it all the time, real tight on its tuning, so came up with the idea to set it up on a mount an make it track the ark, an it works great, an what a learning curve this was. an I will try to share it with you for any 1 thinking about a H-2-H mount or polar mount.
Now all pictures are from my test pole in the ground 5 1/2 feet, an here I can get from Gal-18 over to Telstar-12, an can not get all transponders due to boat for T-12 an a tree for G-18, but can get most strong transponders.
now my 1st try to get it to track, I failed big time an was ready to cut this mount up an remake it if I had to. but after getting on the compt an doing some research I found out what I was doing wrong, all thanks to the Prodelin web site, read their instructions for a polar mount for a 1.8m dish, an with in 3 hours had this thing tracking great.
now this is how you need to treate a Offset-ku dish to track.
1st you need to find you're declination for you're given area, then add that to you're offset angle of the ku reflector, now you will add you're declination an the offset angle together this is you're declination adjustment, should be some thing like this 23.5 offset angle of dish + 3.9 declination for you're location = 27.4 degrees of declination to dial in. now this is how you set it up.
1st you will set you elevation of where you dish mount is going to pivote from to 90* or perfect vertical, now set you declination to what you have determined from a flat spot on the reflector to ( my case here 27.4*), an "Don't Move It" this is where I messed up. now set you're elevation to you're latitude of you're area. now you are ready to start checking signal, an treat it like a C-band now or a prime focus dish start with you're due south, peak it in for best signal using you're elevation adjustment, then you're far east an west, to max signal an snug bolt up on the pole cap, now go back to you're due south satellite an re peak it again with you're elevation adjust. now if you took the time set you're declination perfect from the beginning, you will be done in no time.
Also with these lager offset reflectors the beam is tight so I found it fairly easy to get it perfect, after I read the Prodelin manual. my first mistake was moving the total declination adjustment.
now if it doesn't track for you, go over you're declination adjust agin an make sure you have it dialed in right. an if you do an still not tracking, now either add 1/2 of a degree or take away 1/2 of a degree (keep note of wich way you go if you make it worse), now you will need to repeat you're due south an east to west peaking process all over agin. remember changing declination adjust mess all of you're previous peaking that you have done.
when you finaly get it, you will have 1 nice set up, where this 1 is going should be able to go as far west as i need (148 will not use it but it could hit it) an east to AltanticBird-3 might even hit Intelsat10-02.
in these pictures all mounts that where added to the CFI H-2-H mount are stainless steel along with 2 angles on the reflector, (this is all my welding an fab work, some done Tig an some stick) an all stainless bolts an nuts also. down here where I am at any thing will rust away.
