RG6 is a coax cable that is designed for radio frequency (RF) signals. These are the signals received by a TV antenna or an LNB. RG6 has only two conductors

HDMI signals are digital signals and the full HDMI standard requires a 19-wire connection. The only way to pass an HDMI signal down 2-conductor RG6 is to use a modulator which essentially takes the digital signals and encodes them on an RF carrier frequency.

Regardless of whether one uses the wireless system being discussed in this thread or the wired system I posted, both systems operate in this manner. The digital is encoded on an RF carrier and then is demodulated at the receiving end.

Satellite receivers used to have coax cable outputs but those were standard definition only. HD receivers don't normally have coax outputs anymore probably because most people don't use them. If you don't have to worry about how to string a cable through an RV, it is actually much easier to use HDMI cable for long distance runs because the digital signals aren't degraded by long cables nearly as much as are RF signals.

While picture on 42" is not near as quality as the HD 46" (newer Sony model) it is very nice and seems to suit wife to watch while on treadmill. You may be surprised. Hope so, then you will have a much simplier solution for bedroom TV. Let us know.

I believe if my HDMI wireless went out for the RV bedroom TV the picture on the 32" there would be adequate if I just used optional coax plug as I do on the home set-up described above.

Good luck with project.

I did the install yesterday and everything turned out great. I replaced the bedroom 21 inch SD tv that preformed very well using the RV coax attached to the HD receiver up front.

First I hooked the 26" HD Samsung to the existing coax and the picture quality, as expected, was acceptable and much better than than the 55" I first tested with the coax setup. In this case smaller is better. However, it only operated in the SD mode while tuned to HD channels.

Next I set it up using the HDMI Wireless system and "wow", HD picture every bit the excellent picture quality of the front tv using HDMI cable. I left the coax hooked up as a spare input "TV" if I needed it. Except for no HD, I would be very happy with just the coax hook up.

Overall I would say the wireless HDMI is the way to go on a bedroom setup as it took me apx. 20 minutes to do the initial hookup. I used the Actiontech "my wireless HDMI multi- room" system. I tried it first because it was handy, sold at Best Buy but also at AMAZON.

If if one wants, you can buy another receiver for an outside TV. I was in a hurry and still want to compare "IOGEAR" wireless system to the Actiontech as I have 30 days to return it to Best Buy.

If anyone has more information on these Wireless HDMI systems as to features, options and why one would be preferred over another, it would be great to hear your thoughts. This wireless stuff has really got me thinking for other projects.

Good to hear -- your experience is consistent with other wireless HDMI users I've heard from.

Keep us posted if you compare with iogear. I plan to try this on an outdoor setup using the dish vip211k receiver on the inside of the motorhome.

Our 15" Dynex TV in the coach bedroom specifies in their use guide manual that coax must be run from the receiver box RF OUT (in this case--Directv) to the RF jack port on the back of the TV using RF coaxial cable (75 ohm)
I had tried hooking up the UHB method while camping 'cause I had left the Dynex user guide at home. It didn't work

Depends. If you're using a receiver-to-TV RG6 RF output, then the best signal you can get is SD.

However, if you're using Dish or DirecTV dish-to-receiver RG6, then it's a different story. The RG6 transports HD from receiver to receiver just fine.

If you have a single receiver and want HD in two places, then stringing HDMI makes sense because you're essentially copying one signal. Otherwise, stick with RG6 when you can -- both DirecTV and Dish use RG6 in their whole house DVR systems to carry data and picture.

After looking at the specs and reviews I just ordered one of the IOGEAR units from Costco.com, they are on sale until the end of September, if it doesn't work right, I can always take it back. I'm going to put it on my outside TV as the RF cable doesn't give that good of a picture.

I'll post when I get it up and running.

I just had a Dish Hopper/Joey system installed in my house yesterday to replace my "old style" individual receiver DVR system. The key thing that relates to this thread is that the new technology allows a remote TV to get the HD signal over the existing coax. The Hopper (main unit with the DVR in it) feeds a signal back through the coax to the Joey (remote unit) and the Joey has the HDMI output. If Dish will allow it, this would be the best of all ways for a RV with more than one HDTV. The satillite only connects to the Hopper unit and it can have up to 3 Joeys connected to it and they all share the DVR.

Dish allows it. Myself & several others I've seen on the forums have Hoppers in our RVs.

DirecTV also has a whole house system that could be used in an RV.

Can you have a House system and a Hopper in the RV under one account? Also will the Hopper sat. receiver work with Dome providers? I have a KVH which is very particular to the model of receiver used.

I wanted to use the Hopper but was told by Dish Net. I woul have to have two seperate accounts but I think I told dish I wanted to keep my 211k for the MH as I mainly use a portable 1000 dish for the RV tv.

Also , asa quick update to the thread, after testing the Actiontec Wireless system for a few days now, I'm finding problems with it. I have on order the IOgear and will test it soon an will likely return the Actiontec.

Maybe one of the Modulator/Demodulator systems, expensive, is the way to go or just byte the bullet and install new HDMI cable?

You can now have a Hopper and the 211k on one account.

The Hopper is supposed to be connected to a dish with 2 lines out because a Hopper has 3 tuners -- that means a rooftop Travler, 1000.2, 1000.4, and even a pro 500.

I don't think the KVH will work with a Hopper.

[QUOTE=TechWriter;1312917]You can now have a Hopper and the 211k on one account.

Now you've got me thinking again about the Hopper for the House and 211k for the RV.

Are you happy you switched to the Hopper? What do you like about it and are there any negatives?

I switched from a 722k and two 211ks.

A Hopper and 2 Joeys replaced these, and now I have a 2 TB whole house (or RV) DVR which I can access from any TV that is connected to a Joey.

Plus, if you enable it, PTAT (Prime Time Any Time) will record all network programming, every day in prime time.

Hopper also has better Internet connectivity than previous Dish receivers.

All this in an RV. I have the DirecTV whole house DVR equivalent in my stick house.

No regrets.

That is the way I am going (Hopper in the house and 211k in the RV) because when I started this I didn't know the Hopper would work in the RV. I just got the 211k today and will get it hooked up in a couple of days. I am using a TRAV'LER SK-1000 dish system so it's the same as the house. I do not know if any of the domes would work with a Hopper as the installer had to change the connector in the wall to a "better" one. He said the Hopper requires a cleaner signal. There is a special hub that is needed for the coax network. If I had it to do over again I would go with two Hopper systems, two in the house and move one to the RV when needed.

My Hopper only uses ONE coax from the satillite dish so two are still available if I want to add another Hopper. I am still getting used to it but so far I like the Hopper system better than the 622DVR, 722DVR and 322 (that was moved to the RV) that I used to have.
