directv satellite service? Am I offer more than one receiver or do I have to buy them separately at my expense if I want more than 2 tv's with access to service from directv. Does dish network offer more reception without cost?
You need a receiver at each tv location to watch Directv.
Dish Network has what is called a "dual tuner" receiver which you can watch on 2 separate channels with one box: http://sathookup.com/dish-hd/dishhd-receivers.php
The most popular are the vip722 and 625 which is a standard DVR.
Both companies offer receivers with two tuners that will feed two TVs. If you want more than that, yes you have to get more receivers. Yes you have to pay for or lease them.
Cable companies do the same thing for cable converter boxes.
