Roxy,

as the author of the post you can go back to the post and edit the pic size. 400x300 seems to be a good size (for me because my pcitures come in at 800x600). The preview will give you and idea of the size.

So even though you a have a small file size, sometimes the photos can be large.

GREAT PICS BTW and now that you gone this far, I waiting eagerly for the other PODMODs

Roxy, wow, that's alot of coax splitters. If I recall correctly, every time you split the signal, you loose between 1.5 to 3 db of signal strength. I would be interested to know what kind of video quality you get on the televisions. Please post some pics of the final hookup with TVs and all.

somewhere I posted gigantic pictures of all of the splicing. Yes, I lose some of the quality but it didn't look too bad the night the dish pro checked it out. I have ordered a new Westinghouse model-16 inch that can be mounted on the wall or under a cabinet. It looked great in the store. I'll know more when it gets here. I ordered from Amazon.com My large 22 inch has a direct line. It still had a great picture.

On a good quality 2 way splitter you have about a -3.5db loss per split. So you lose -3.5db on the first split, will have lost -7db total on sets after second split, and -10.5db total for sets connected after last split.

So that is 0.447 (under a 1/2) of the original signal for tv hooked up to first splitter

0.200 (1/5) of the signal to tv hooked up to second splitter

0.090 ( under 1/10) of the original signal to tv's after 3rd splitter.

If you have signal problems on the TV's you might want to consider getting rid of all the splitters and go with an amplified distribution system like this:

It has adjustable gain, and should allow you to deliver consistant quality video to all your sets, and you won't have the signal loss problems you might have with the splitters chained like you do.

Radio shack usually stocks those in most stores. Which gives you the benefit you can try it out and if it doesn't work out take it back. You would need to plug the amplifier into an AC outlet.
