I have a 721 receiver which I use the coaxial video out to route the signal to additional TVs in my basement office and bedroom. I recently added a surge protector to my bedroom TV. Since adding the surge protector the video quality on the my office and bedroom TVs are significantly worse. How could improve the signal to both of these TVs?
Thanks for any suggestions.
In addition to all the great advice you've been provided so far, be prepared for less than great RF from the 721. I have RF from my 721, 625, and 322 running a short distance to another room, with a good signal amp. While the RF output on the 625 and 322 are consistently good, the 721 stays true to it's freaky nature and provides at best noticeable analog noise. Also, depending on what mood the 721 is in
, you may find quite a bit of noise out of the 721 RF. I have found that a re-boot seems to restore, most of the time, the 721's RF output to it's usual sub-par but watchable RF signal. Ironically, it is my mother who watches the 721 RF in the extra room, and the noise does not bother her in the least; she just wants to see the show. Fortunately, it is I who watch the far more superior 625 and 322 RF in the extra room.
This may go back to how poor the RF outputs were on Dish's older boxes, including the 721; they were noisy. I have to say, however, that starting with the 301 on up, Dish RF outputs are now quite good. The dual tuner boxes seem to have the best quality RF outputs of all. And, the quality of the TV's RF demodulator will also, greatly affect the quality of the video on that 2nd TV. My 2 Sony's display a
BEAUTIFUL picture via RF, while an old JVC and RCA stink when it demodulates the RF.
Best of luck to you.
