How low does a signal have to get before you start seeing the picture drop out?

Depends on the receiver, I'll lose the signal on my H10 around 50- 60% on a clear day. Of course if you're at 60% on a good day, then even the slightest sign of rain will wipe you out.

Usually below 50.

I'm watching a channel with only 58 strenth due to rain, and I'm not getting any drop out.

For me, moderate picture and audio drop-out is apparent when my 811 receiver registers a local digital channel's signal strength between 72-74%. More severe pixelation occurs between 61-71%, to the point of the channel being unwatchable. My 811's signal strength meter defaults to 49% for anything lower than 61%. 49% is a black screen and is equal to 0%.

Ideal signal strength is in the 75-93% range at my location. I've never seen the meter register higher than 93%, and that was just briefly. On strong local digital channels, the meter is usually fluctuating between 89-91%. But it is possible to have some brief pixelation and audio drop-outs even on channels registering 89-91% - the meter will quickly fall to a lower number and bounce back to 89%.

The threshold for picture drop-out at your location will depend on the transmitting power of your local digital stations, the distance and terrain between your location and the broadcast towers, and the type of antenna and receiver that you have.

the local channels on my hughes SD receivers work even when the snow brought the signal down to 19. it would jump from 19-24 when it was snowing and the dish was covered with snow. just a few of the other channels worked, but the locals never did go completly out. the picture was degraded slightly but it was watchable. my samsung directivo and my old rca lost all signal. i have the phase 3 oval dish.

depending on location. ideal signal strenght is at least 70% sat 119 transpnder 19 sat 110 transponder 21 if you have winged sat locations sat 105 increased to 54% sat 129 same. customers in alaska hawaii puerto rico and the virgin islands differ. rain fade may drop signal down about 5% watch for freezing weather!!! if ice builds up on dish, will reflect signal out
