In eastside Portland, we are served by Rogers cablesystems (Basically a Canadian company with franchises around the U.S.). They use the Zenith Z-TAC converter box. The video is noisy and sometimes not watchable. I have an excellent picture off my outside antenna and prefer it to cable for watching the locals. And the cable company tells me that I have a good signal level. > I live in St. > Louis city, and get ghosts and color flicking in and out on just about > all channels, using both an attic antenna, coax fed, and rabbit ears. What is your antenna doing in the attic. I am not surprised that you have ghosts and problems. Put it outside above your roof where it belongs and you will probably see some improvement. Attics are for insulation, house wiring, pipes(exhaust vents), spiders, and other bugs. not antennas. Who knows what reflections and attenuations you are getting from your attic. > > > I understand from people who have cable (not due in my area for some > years yet) that it is no magic solution to these problems, either. > Cable signals are often poor, also.

I understand the problem for me may be in the Zenith box. Everything is scrambled. When you select a channel, it determines if you have paid for it and then descrambles it and demodulates audio and video. then they remodulate it to CH3 or CH4. If they supplied you with audio and video out it would not look bad. However, The Zenith modulator seems to be a piece of cheap junk. Anybody else have this problem with Zenith Z-TAC??? Because our system is two way interactive, there are no repeaters or amps between the front end and myself - 15 miles by crow, who knows by cable??? Doesn't seem to matter as people within one mile of headend have same problem. > >That is why I had looked forward to DBS! Think of it; a quality signal >beamed directly to your home, without the thousands of echoes Ah yes, satellite TV. Actually the best quality signal you can get for broadcast. Nice until they are all scrambled. jim
