1. They DO make Component and HDMI splitters to run multiple TV's from 1 source. Tiffin has used the system for 4 years.
2. The COAX cannot transmit HD signal from a source. But CAN transmit the Over the Air local HD sugnal and you will get HD from over the air signals. There is NO Coax output on Sat HD boxes, only on Cable systems. On Cable systems with coax OUTPUT, that cannot transmit HD signal, just SD signal to the TV. Doug
I do have an HDMI splitter, which I have tried, and it will NOT allow two TV's to run off of a single satellite box. I can run one TV or the other, but not both at the same time. What I mentioned about coax being able to carry the HD signal is exactly as I said. My Winegard SK-3005 HD satellite antenna is connected to my DirecTV box by a single COAX cable, so obviously all of the HD information is being carried from my dish to my DirecTV box. It is changed within the DirecTV box so that the only outputs are Component, S-video(neither of which are HD, and a single HDMI output.
You are confusing INPUT from a source with OUTPUT. The Input from your roof Winegard is NOT HD but an electronic download signal to your Sat HD receiver that then converts that electronic signal to a HD video. That then MUST be transmitted in only 2 ways for true HD--Component or HDMI. As I stated, IF you want to spend he money you can buy Component and HDMI switching systems for multiple HD TV's from a single source. They are NOT cheap. Doug

Well that's not exactly true. We have a dishnetwork two TV DVR box and it does have a coax outlet. Otherwise how would you operate the 2nd TV off of it. And the TV in the back shows the strength and type of signal and it does show that some of the shows are at 720i.

yes u put a splitter system in so one HD box will supply any number of tv,s.My allegro bus comes from the factory with a HDMI splitter system and i have HD TV at all 4 tv,s.Now if u want different channels then us need seperate receivers.the difference on HD verses regular TV is very noteable

NO , YOU are wrong. There is NO WAY to transmit HD in ANY form over COAX cable. Whatever and Whoever set up your system may have used COAX to the other TV, but it is NOT HD, regardless of what you think the TV display tells you. That said, that "Coax" may also transmit local antenna signals and your TV CAN process that. But regardless of ANY type system, COAX CANNOT transmit/transfer TRUE HD. PERIOD. Doug

Maybe with Direct, but my Dish 211k (a newer receiver) has HDMI, component, composite, and coax outputs. So you could connect 3 TVs to it if you wanted. Of course you'd all be watching the same thing.
You need a HDMI splitter such as the one pictured below.
HDMI 1x2 Mini Splitter, Full 1080p v1.3 for HDTV PS3 XBOX Blu-Ray DVD DirecTV
HDMI Distribution Amplifier (1x2)
Introduction:
The HDMI Distribution Amplifier (1X2) is a two outputs HDMI splitter
It distributes the HDMI input into two identical outputs.
These tow outputs are synchronized.
HDMI Distribution Amplifier (1X2) has the ability of buffering and amplifying
Series connection of it achieves long distance transmission of HDMI signal of more than 15 meters
When two or more them are cascaded,they can be used to create a larger distribution,it offers solutions for HDTV retail and show site
HDTV, STB, DVD and Projector factory, noise space and security concerns, data center control information distribution, conference room presentation school and corporate training environments.

Interesting
My Meridian has a Winegard Traveler (Dish Network) and 2 VIP/211 receivers. The front 211 receiver is running (2) front TVs that are connected: 1) HDMI Cable 2) Component (RGB) plus R/W for sound and the outside TV which is also Component (RGB) + R/W. The rear 211/TV is connected via HDMI. ALL TVs are running HD (720P).

So, what good would this be for RV use? Since it has identical outputs you'd have to watch the same program on both tvs. I'd much rather have the ability to watch different programming on each tv even though its not HD. This to me is one of the main reasons in having a tv in the bedroom. I cannot watch the same programming as the wife does. A fella can only take so much dancing with the stars.
