dh8200u lost station

[barrybrooks1]

This weekend I installed a hd8200u. I live 75 to 100 miles from transmitters. My signal strength has improved for most of my station and I now pick up stations I could not before, but one station I do not receive any longer. Before I changed antennas this was my strongest station. the is channel 9 (RF 11) and band Hi-V. Does anyone have any ideas what I can do? Maybe I did something wrong in the installation?

Could you private message me the complete address and the station you are trying to receive?

Thanks,

Good morning barrybrooks1 -

I apologize for coming back to you with more questions but technical services would like to know a little more about the situation...

Can you tell me how high the antenna is mounted above the ground and does it have an amplifier such as a preamplifier or distribution amplifier installed on it. How many TV sets are you running signal to and what are the lengths of your cable runs.

Winegard,


I have a preamp, and a distribution amp. I have only one tv hooked up at this time. The antenna is about 30 ft above ground. Not sure how long the cable is maybe 40 - 50 ft. The thing is that all these items are the same as before I installed the new antenna. If you need any more info please let me know and thank you for your help.


Thanks,

[winegard]

Can you give us the manufactures model numbers of your preamplifier and distribution amplifier? Try bypassing the distribution amplifier and go directly from the preamplifier output to one TV set and check your picture quality. It may be that we have too much signal on channel 9 with both amplifiers that the digital tuner can not handle it and will shut down.

Response from engineering...


For the distance to the transmitters, the customer requires at least 50 ft. to 60 ft. of antenna elevation for reliable DTV reception. The earlier antenna may have worked because of conditions that favored signal reception of Ch 9.1. It is possible that another location on the roof top or a small change (up or down by 30" from the present antenna position) will restore Ch 9.1. Again, reliable DTV reception at distances of 75 to 100 miles requires considerable antenna height and locations free of trees/obstructions.
