    Declination Angle

    I know calculation is a hard way to get all these information when you can get them in seconds on the net. but i'm a pilot & flight navigator and I have learned & accustomed to do every job on it's standard way instead of relying on the internet & website's. That's why i rather to solve such...

    Declination Angle

    You're absolutely right, earth isn't sphere & earth radius is variable from equator to polar, if you want to get an accurate result you need to get your latitude radius & also distance to your desire SAT first before using this equation. I just put 3964 & 22300 values in order to write the...

    how do you set the elevation

    Put a digital or analog inclinometer on your reflector rim, if you read 18.6, then you have reached to your desire SAT. Ali

    Prime focus ver Offset focus LNBs whats the differences?

    There's no difference between prime focus & offset LNBF except their scalar's. if you are using C band LNBF for offset reflector, is better to take conical scalar ring & flat scalar ring for prime.

    Anyone interested in an 8ft offset dish?

    What an awesome reflector, if i had enough space i would buy it.
