I bought a Samsung UN22D5000 two days ago to replace a Samsung LNT1953H TV/Computer monitor. The older one has two F connectors for coaxial cable, but the newer one has only one. Because I like to have both an over the air antenna and DISH network, I need twin coaxial cables. I bought a cheap Philips A/B this weekend and found it to be very lossy. Some much so that when I connected either cable by itself everything was fine, but simply adding that switch and a short 3 foot run of RG-6 the over the air channels pixelate. I suppose it could be the patch cable or the switch. At any rate I am know wondering if all A/B switches are created equally, or if some are more lossy than others. And, if that is the case, what are some better switches that won't lose as much signal?
Simple answer is why are you running coax from your dish box to the tv in the first place? Use the HDMI, Component, Svideo, or Composite. Any would be a huge improvement in picture and sound.
The DISH 722k modulates on either NTSC or cable channels, so I selected to cable channels and I have RG6 on all three levels of the house to tune in either TV1 or TV2 content from the DISH satellite receiver. I suppose I could replace the RG6 with multiple runs of HDMI, Component, Svideo, or Composite, but I think it would get pretty expensive. I think that it would even be better if the 722k sent it out via ATSC through the RG6 that the recovered content would be better, but I doubt that will happen.
