Receiver around 200-300. Dish and lnb around 50-100.
You need also cable and other accessories. Around 10-20.
You also need to know how to program the receiver and setup the dish. That is pricless.
So in my opinion, if you do it yourself, go to www.al7bar.tk to read, read, read.
Hire an installer, around 300 dollars or up.
The receivers will only work temporarily. Basic aim to Dish network 121 west satellite. Linear polarized.
