Sat TV: your choices in the US are Dish, DirecTV (non-HD) and DirecHDTV
Antennas come in 5 types. Rooftop Mounted In-Motion (DOme) and stationary Dome (Why?) Rooftop Dish, Protable Dome and portable Dish.
DOME antennas work 100% with DirecTV (non-HD) do not work for DirecHDTV as far as I know. Does not matter if stationary, in-motion or portable.
DISH antennas, you get the dish that matches your service, and it works, 100%
Dishnet: Both HD and non-HD, uses multiple satellites (3 for HD 2 otherwise out of a total of six or seven). Now the problem.
With a dish type antenna. they work, period.
With a dome type (Again stationary, in-motion or portable) a VIP-211k, for example, will work provided the dome is able to accept "Change Satellite" commands from the receiver (The Dish Tailgater is specifically designed to mate with the 211K)
Multi-input DVR's however. or Multiple receivers.. Do not play nice with Domes on Dish.. Even if the dome is a "Dual" (Able to feed two receivers at the same time) as if you wish two shows, not on the same satellite, there is a conflict.
With a dish type antenna, no conflict since the 1000.x dish sees all 3 birds at once.
Finally Rooftop or "portable" Rooftop antennas are nice, you park, push a button and instant TV.. UNLESS YOU ARE PARKED UNDER THE EVIL SIGNAL EATING TREE (I phrase I coined based on the Evil Kite eating tree of Peanuts comis strip, and which I'm starting to see others use.. Thank you others).
So if you have a roof mount, also get a portable, and put an A/B switch in the LNB lead to the recever,, A goes to the roof mount up Above.. B goes to a connector down Below, either a Bulkhead (Through wall) connector, or a ground Block in the Basement or in my case a dual ground Block on the Brake Bell crank Bracket.
Beyond that it is all packages and price, and I can not advise you there.. I want to get just network and perhaps one or two "Cable/Sat" channels but alas, they make me buy like 40 stations, 35 of which I could care less about .. This is a rip off.
Consider Over the air TV, Most of the time I have over 2 dozen stations including all the ones I want. No problem.
Home was where I park it. but alas the.
