African Satellite World and Sat Gear

I lost my Premium Free channels on both 7/68.5°E, is it general or might there be an issue with my setups?
 
Kwa dar es salaam hzo decoder za star sat nitazipata wap? Duka gan k, Koo wanauza?
 
yaan nikiingiaga humu sielewagi chochote
Mbona rahisi tu ya kawaida haya.. 😂 😂 😂
Unatakiwa kwanza ujue hizi hisabati hapo chini, halafu urudi humu ndio utaenda nao sawa..🤣🤣🤣

This is the equation used to calculate the azimuth of the receiving antenna azrx:

az_rx = atan(tan(lon_rx-lon_sat)/sin(lat_rx))+180°


Where latrx and lonrx are the latitude and longitude of the receiver. lonsat is the longitude of the satellite.

And this is the equation used to calculate the elevation of the receiving antenna elrx:

el_rx = atan((cos(lat_rx)*cos(lon_rx-long_sat)-(R_0/(R_0+h)))/sqrt(1-(cos(lat_rx)*cos(lon_rx-lon_sat))^2))


Where R0 is the radius of the earth (R0 = 6'370 km) and h is the height of the satellite (for a geostationary satellite, h = 35'800 km).

The following drawing shows how latitudes and longitudes are defined here:

Receiving antenna azimuth and elevation are clearly shown in the following drawing:

Focal Point Calculation​

How to find the focal point of a VSAT dish
Antenna Focal Distance Calculation

FL = D² / 16d​

Focal Length = Diameter / 16 x depth​

D = Antenna diameter
d = Antenna depth
FL = Antenna focal length (prime focus)

Just buy the decorder for the scrambled channels to watch the channels, Size matters.
