Hmm, I overlooked the fact that you were splitting it to two separate locations. The 2250 has two ATSC tuners. If the 1600 also has two ATSC tuners, it is also splitting the signal internally, 2 ways (4 splits total). However, if it's only a single ATSC/NTSC tuner, it is not split, which might explain why it works better. It's also possible there is just less loss on the bedroom run. Regardless, at your distant location from KFTA and the likely number of splits & coax involved, you definitely need the 7777 preamp.
As for the type of coax, I'll need to get up there and look. I'm thinking it is RG6 because when I originally had U-verse installed the tech had to replace the line between the two rooms since the original cable couldn't hold a strong enough signal to connect the receivers together. Now I'm just using that same cable for the antenna because they conveniently had a junction point right where I needed it.
BTW, do I have to figure for loss on the junction points also? There should just be one on each connection where it comes out of the wall.
Your splitter needs to be a 2-port splitter that goes up to at least 700mhz or higher. It must also pass DC on one port and block DC on the other, to prevent damage to a tuner and/or the preamp power supply. Example here:http://www.thesatelliteshop.net/5100...ng-p-1562.html
By junction points, if you mean a wall outlet; if they are in good shape, the loss there should be negligible.
