Ya, it's even worse now with the price of copper through the roof.
$350m for a bird is nothing compaired to billions in coax, line install crews, distribution amps and bucket trucks, employees ect.
Plus the sat company makes you buy the receiver, but they usually give you a free $75 install.
If they were smart they'd cut the price to $10, increase their subscriber base and get that much more money for advertising. This would kill off any competition in a few years.
