What i can advise is to look for local installer who is experienced and learn from him .... get the basics first ... i was in your position once and i thought i could get any satelite i want ... but i eventually realized that isnt the reality ... and thats the fun in this sattelite journey .... i learnt from someone and am not perfect bado but i can get the common sats with ease now akina ISO 20,Apastar,Nilesat,Nss12 and many others .... but i am still learning
Again my advice to you is get someone who is experienced in your locality and learn the skills from him/her
Hope you take this info with a good heart.
