Upgrading old Dish 500 system to HD

[slicked25]

Well after switching TV's they worked flawlessly. I don't have a TV remote to the heavy TV that I put back in my room but I can't get the channel below 25. I'll rig something up.

is this older tv rca brand, if so check the f connector on the tv

She's fixed. Found an all purpose remote and onced programmed to the heavy TV went in to the menu system and turned off the cable. Put it on ch 22 and worked like a champ.

RG59 will carry the 18v at 600 milliamps that DPP requires.

Some may, some will not. "Economy" RG59 is made with a 22ga CCS center conductor which is not rated to carry that kind of current when used in an insulated cable.

By the same token, there are RG59 cables that are sweep tested to 3GHz.

Ok. And what are signals made of?

Here's a hint:

DbmV.

The signal drop can be quite a bit and still provide a signal the box can decode. However, once the voltage supplied to the LNB drops too low, the LNB won't operate.

True, very true. But you'd need a really long line to drop the voltage to the LNB that much so that it wouldn't operate.

I am still using my original Dish 500 with twin dual LNBs, and a wing sat Dish 500 with one dual LNB, both going in to an SW64. The wing sat dish was pointed at 148 but I repointed it, first to 61.5 and now to 129. I started out with two receivers, a 3800 and a 2700, and now have a leased 622 and an owned 508. I have done all my own wiring, even on the original install. It is all still working just as well as it did when I first installed it. Legacy LNBs and switches work just fine with HD receivers. You just have to have a separate coax for each tuner.

If you're using copper cored RG59, the DC resistance is under 3 ohms at 200'. If your using CCS, that number soars to 14.7 ohms.

You know, that's why all the cable I wired in my house is solid copper core. Everything we carry at the office is CCS. >.<

Sorry 'bout that

After accidently hijacking the thread to ask why RG-59 is bad, I went back outside and looked at the cable. Yep, it's RG-6.

DOH!
