Dual Purpose Dish?????

06-09-2005, 12:37 AM
I have been a DTV customer for 10 years. I have recently lost my sattelite signal due to trees. I have had 3 different DTV installers out to try and find a better location for the dish, no avail.
Before I had this problem I purchased a brand new eliptical triple LNB dish for DTV. I am now going to switch to Dish Network becasue of a better signal on D, network. My question is, will the dish I purchased for DTV work for Dish Network? I know they point at different sat's but it would definately save me some money.
Thanks for any help !

Your best answer would come either from a call to Dish, or from a Dish forum.

Hearsay: I've read this discussion elsewhere, obviously you aren't the first to consider it. If the hearsay is accepted, the answer is: No, they use different LNB's.

Have you considered cutting the trees?

Or putting the dish higher? You may not need extreme height to get over the tops. I put mine on my antenna mast. Of course that only works if you have an antenna mast....

Thanks for the idea's. I would hate to leave DTV... Cutting the tree's is out of the question. How high could I go with the dish, thats a thought which I have thought about but did not want to go through the hassle of putting everything together and not having it work. I have spent way too many hours worrying and trying to make it work . I would like more info on raising the dish up. I have an open line of sight on the Azimuth, just the elevation is the problem because of the trees. If I go quite a bit higher, it might work. How high can I go, within reason..
Thanks again !

You do not need a new Dish. DTV and DISH use the same types of dishes for HD (18 inch oval). You will just have to point it a different direction.

Also, how high you have to go depends on how close the trees are to your house. Do you have the dish on your roof now? If not, that's the first place I'd start. If you have trees higher than your house I'd say ur lucky to ever get a signal in the first place.

If it's already on your roof, the best way I've seen it done, and this depends on if you have a home owners association that lets you do this, is to mast a pole (any metal pole from Lowes or Home Depot, or even wood will do), and put the dish on that and attach it to your chimney or house frame.

You can also do the pole from the ground, although that would be a pretty big pole.

Lastly, do you have clearance behind the trees? I've seen people mount dishes in actual tree trunks up high and run the cable down the tree and bury it in the yard. May be too excessive, but I've seen it done.

I wouldn't recommend tree mounting, trees grow & blow in the wind...

I'm sure someone here knows the max cable length for a dish. That is your only technical limitation (I believe) to how high you can go. There is, however, a physical issue - the dish will present a significant wind resistance. If you put it on a pipe or mast thats too flimsy you will need to learn some new cuss words to adequately convey the feelings it will give you. If you use a chimney mount, be sure your chimney is structurally sound or you will provide hours of entertainment for the neighbors. It may be prudent to have a pro give you an estimate. That way you'll have someone else for your wife to holler at.

When I quit installing for DishNet about 2 years ago, the max recommended cable run was 200 ft. from the dish. After that, we would install relatively inexspensive inline boosters available from Radio Shack (about $15). Personally, I was able to successfully install about 300 ft of coax with no booster and still receive about 85% signal strength at the receiver. Quad-shield coax will carry loss free for quite a distance.

I have seen some strange mounting solutions, but the best for height are poles strapped to chimneys. Any standard chain-link fence line post will do, it is the perfect diameter. I have found these in 10 foot lengths, and I believe they are available in 12 ft. by special order. One post and about 4 steel bands will work nicely.

The highest dish I ever had the pleasure of working on was bolted to a 75 foot aerial tower behind a house. The OTA antenna was of course at the top, and the dish about 10 feet from the top. These are available from a variety of sources, Radio Shack used to have them in their catalog and may still. www.Tessco.com (http://www.tessco.com) is also a good source.
