Well, it's not useless, but I know what you mean; for cable and satellite.

I prefer an all-copper RG-59 for anything other than RF.

I did that in my parents house. The master bedroom was about 120 feet from the garage where the distribution panel was. My Mother wanted 4 CATV jacks so she could move the room around and put the TV in any corner. Instead of running 4 separate runs I ran one run to the closet and installed a left over 6X6X4 box in the wall. Out of that box I ran the short runs to each corner of the room and labelled the wires. Now if they change the room around they simply have to change which one of the 4 runs is connected to the F-81 barrel.

There are reasons for homrun outlets.

Everyone talks about dB's. A decibel is nothing more than a logrithmic ratio that represents no absolute value unless referenced to something ( ie dBmV, dBm, etc ) What does that mean? -3dB equates to about a 50% power loss & 3 dB equates to a 50% power gain. dB= 10logP1/P2 or 10logP2/P1 - depends on whether your'e talking gain or loss.

Also alot of converter boxes, DVR's, & especially cable modems & EMTA's are two way devices with variable return RF levels. However they cannot output an infinite amout of RF power which means return path loss must be minimized to ensure they operate in their " sweet spot" in order to maintain a decent signal to nioise ratio at the receiving end. A bunch of cascaded splitters creates alot of insertion loss in both the forward & return path.

Who cares. Just homerun them all like I already said and you can't go wrong. Nobody cares about the dB's and RF gains and losses. It doesn't matter if you just homerun them all.

well said

I alway run two cables.

I should say, one cable back to the Headend, is for the computer, like wise with the phone wire cat5e.

T.V.'s will work with a splitter, but computers not so well.


Two bedrooms, one has cable, the other doesn't, put in a splitter, and run
the cable thru the adjacent wall, T.V. should work fine.

With computer it becomes a distance game, number of feet away from
the headend. And alway used a good brand of RG-6 CABLE, with compression fittings. And if your install boxes, use the open end ones.

I just did a job, where I had to open the wall, installed CONDUIT, then after the dry wallers finish the wall, had to ruN HDMI cable along with a Triple RCA Component HD Cable.

I just wanna know, were all of your previous posts this past week, a put on? Because you didn't spell or use grammar worth a lick, but all of a sudden on this post, you are almost perfect. What's up with that? Maybe you've been drunk all along and now you're sober?

No, I think you're drunk now, because I can't make heads nor tails of half of what he said.

Hahaha! Well actually you've just reminded me that I need to run out to the grocery store and pick up another 24 pack of Corona! I drank my last one on Wednesday.

While partimer doesn't make his posts perfectly clear, at least this one has no spelling errors that I noticed. This post doesn't even look like it was authored by him.

drsparky

doesn’t

Ahh yes. Good catch. I need Corona! That's what's the matter with me!
