We just bought a house that is wired for a Direct TV dish. I don't want to use that, rather, I want to use my OTA antenna for HD. Can I use the current satellite wiring for my terra antenna? The dish has about 3 cables coming off of it, which one would be the normal coaxial cable that I would use?

Thanks!

There were probably 3 DTV boxes in the house, with a cable leading from the dish to each box. If you just want one TV, you'll have to figure out which one leads to that room.
IF the cable lengths are not too long as to require a mast preamp, you could combine the 3 on the roof with a splitter and send the antenna signal to all 3 rooms.
One more thing, if the cable is RG59, it might not be good enough. It should be RG6 if it was installed by DTV in the last 10 years.

Perfect, this is exactly what I need to know. Thanks so much!

Hi,

I have similar questions.. I saw your answers. But I have few questions from this topic -

1. They said - antenna signal will be weaker after it got splitted - I have DirecTV for four of my rooms. I am going to cancel it this month.... so I am worried that after installing the OTA outside antenna, signals going to each TV will be weak.

2. If I put an signal amplifier, it will have to be outside and no power. The way DirecTV is using, they have power on one of their receiver cable. Does it work the same with antenna ? or it has to be from antenna to before the splitter ?

Please advise!

Regards,
Edgar

I don't see how an amp works without power. An outdoor pre-amp will need to be powered. But first we need to know what kind of signal you're already getting

If you do need an amp, standard CATV drop amps can be powered via the OUT port, enabling you to locate the amp outside and power it from one of your outlets.

tylerSC 09-23-2012 11:14 PM

You can order a 4 port dist amp from PCT/Channel Master or Motorola, and set it up preamp style with a remote power supply plugged in at one of the TVs. The dist amp will be at the antenna, with one direct coax input and 4 coax outputs going to the different TVs. This configuration works very well in the attic, but if outside you may need to find some sort of protective box to put the amp inside. But be sure and order the separate remote power supply if you use this type of configuration. But if you have power in the attic at the antenna, you can just plug in the dist amp as an amplified splitter.

I also have similar question, My DirecTV was installed withing the last three years, I have an older receiver but just bought an HDTV and would like to get an HD signal but Direct TV wants to put me on a contract, hell with that, Can I purchase the receiver and dish, install it myself and get HD? in other words, is the signal coming from the SAT the same in basic as it is with HD?

No.
You'd have to dig around on eBay for an "owned" receiver.. one that was not leased. DirecTV doesn't sell receivers, anymore. Could run you a hundo or more and it probably won't be the latest technology. There will be a charge for a new access card ($20) and you still get hit with the monthly mirroring fee. You also have to add the HD fee to your account. The tricky part is installing the dish. Not nearly as easy as the old pizza-box dishes as you have to hit multiple satellites. Easier to find an installer who'll work off the books and do it for you for $100 (plus tip). So, that's already $250 at a minimum. And I can't say for sure they won't insist on a new contract with the move to HD. Probably not, but one cannot be sure. This is pretty much the way I've done things and have never been under a contract. I have 3 receivers which means 2 mirroring fees. 4th should arrive today or early next week.

By the way, I edited your post to fit conventions we use here:
DTV = digital television, usually in an over-the-air context
D* = DirecTV
E* = Dish

Hi,
I have a similar problem... had Dish TV and got rid of it recently and trying to install a Clearstream 2V OTA HD antenna and thought i could just reuse the cables that are already running into my living room from the installed dish. But, i spent almost 2 days on this with no luck and i am sure i am doing something wrong obviously but don't know what. So, i would greatly appreciate if you someone can point me in the right direction here. I am a complete novice in running cables and such, so please bear with me frown.gif

This is what i have done till now.

  1. Removed the LNB from the Dish. The Dish LNB had three different coaxial cables running into it. (Sat 1, Sat2, something else)
  2. tried each of the three cables that were going into the LNB to the TO TV hole
  3. In my livingroom, the cable that is coming from outside(dish), is a single wire. It is not long enough for me to run it directly to the TV antenna, hence i went and bought a co-axial cable connector and got another 10 ft cable and extended the wire and connected to the TV

I did the above steps and i do not get any channels whatsoever.. i scanned TV, DTV, Cable DTV, Cable TV options on my LG LED tv but nothing!.

But when i remove that connector which is extending the coaxial cable that is running into my living room and just leave the new 10ft wire connected into the back of my TV (the other end just sitting on the TV stand), it is picking up around 17 channels and the HD channels are very crisp.. So, i have no idea why the cable that is coming from the Dish is not working. Just to let you know, these 3 coaxial cables that are connected to my dish are running from multiple splitters and i am not sure what all is happening there but those 3 cables converge into 1 cable that is coming into my living room.

I would really appreciate if someone can please help me out with this.

thanks
Chris

Most commonly, this means you didn't remove or bypass the satellite multi-switch that's still inline and is blocking the signals.

Trace each the cables from the dish location to their termination. Remove anything that looks similar to a splitter of any kind. Reuse ONLY the coaxial cables.

dudd28 09-22-2013 07:15 AM

Thanks ProjectSH089
So i would replace anything that looks like a splitter with a co-axial cable extender? My dish is almost 75 ft from where my TV is and there are at least 3 or 4 of those splitter like things between the LNB of the dish and the end of the coaxial cable.. I will do that and will let you know how that goes.

Thanks for your prompt response.

dudd28 09-22-2013 07:39 PM

ProjectSH089,
Thank you so much for your help. I now have 52 channels using my OTA antenna with almost 20 of them in crisp HD. I have not seen a picture as clear as this even when i was with DISH. This is just awesome! I saw my Bucs loose really badly to the Pats but it was still beautiful to watch them play such a pathetic football.

If anyone is looking for a OTA HD antenna, i would highly recommend the Clearstream 2V, Its a lil expensive ($70) but still worth it. Once i removed the Dish multi-switch and couple of splitters and replaced them with plain old co-axial cable extenders, it did the trick! Thanks once again for your support and help.

Help with OTA installation?
 
Hi all, here's my issue. Its about two hundred degrees in my attic, so I want to spend as little time in there as possible. I am canceling Directv, bought a Channel Master OTA, and am looking to put it up on the sat dish mast, and use the wires that are already running through the attic to reach my tv's. I have three tv's running now, so I'm guessing there are splitter/switches in the attic 'cause I only see one wire coming off the dish. Should I plan on replacing the splitters with some off-the-shelf hardware? Don't really want to buy an amplifier but the bedroom tv is probably 70' from the mast. Guess I just need to try it and see. One last question, does anyone know if the connector up on the mast is an F-type connector? My D*tv installation is about 7 years old, I hope the wires aren't too old to do the job. Would hate to have to re-wire the whole damn house. Any additional comments/info would be appreciated, thanks!

RoyGBiv 08-22-2015 11:06 AM

The connector at the dish is an F connector. The splitters in your attic or elsewhere in the house will work fine with OTA and are actually a higher bandwidth than you'd get "off the shelf." The biggest issue is your signal strength. How close are you to the transmitting towers, and how many TVs you are trying to feed? If the signal strength is very good, you should be good to go with just plugging the F connector in at the antenna and the TVs into the cables from the walls. If the signal strength is not as good, you may need an amplifier. Getting a plot from TV Fool will help you know what to expect before starting the work.

You'd get more help if you start a new thread and follow the sticky above for antenna threads; your location in the title and TV Fool link in the text. Not much we can do for you right now.

So these are not the "satellite switches" I've read about on the net? If you are right, that will save me a trip to Walmart and a lot of crawling around in a very hot attic! I live about 25 miles from most of the transmitters and I tested the antenna by just hooking it up to a spare tv out on the front porch and I got more channels than I expected. The final installation will be considerably higher up so I think signal strength might be sufficient. Guess I'll just climb up on the roof and see what happens. Thanks so much!

RoyGBiv 08-22-2015 01:05 PM

If you have only one wire coming down from the satellite dish, that means you have a multiswitch at the dish. The splitters in the house would be "plain" splitters and not any type of multiswitch only DirecTV would use.

Took a shot.
 
So, I took a shot and tried to mount the antenna on the sat mast. Damn if the long u-bolts or brackets aren't about 1/16" too narrow to fit around the top of the mast. They are very non-malleable and I'm afraid if I try to bend them, then they won't fit into the holes drilled in the base of the antenna. But I did attach the coaxial cable, just before the thunder and nearby lightning drove me off the roof; I just lay the antenna near the base of the sat mast and got the hell out of there but the good news is that I was able to pick up a couple of channels, so I guess the splitters in the attic aren't switches but just splitters. Anyway, the signal passed through so tomorrow, I'm going to Home Depot and buy a short length of PVC that will fit inside the mast and attach the antenna to that. You would think the folks at Channel Master would know that people are going to mount this on their old satellite masts and provide the right size u-bolts. Not. I will post one more time when I get this all together. Thanks!
