Definition:
-
XX-XX =
Measured signal strength level
-
0-XX-XX =
Signal locks on briefly but keeps dropping out
-
0-50 = Signal
was detected but not able to lock
-
N/A = No
signal detected
Note:
Signal level refers to the Dish 6000 indicator which measures the signal quality
based on percentage of errors. As long as the indicator stays above 48-50%, the
signal will lock. I assume that if you have over 50% errors, the Dish 6000 does
not have enough good signal to decode properly. A reading of 100% would indicate
no errors in signal. I have found that at 47% I will see pixelation in the
picture and below 46% the picture will drop out completely.

I tested a few different antennas to see which one worked best for my
location. I live along the foothills in Burbank and there are two large mountain
ridges that block my line of sight with Mt. Wilson by about 2000-3000 feet.
Multipath is very severe here, some channels I could not get with any antenna. I
made all tests within about 2 hours. I also tested the first antenna (4248)
again at the end to verify that conditions have not changed.

Conclusion:
- 4248 best for multipath rejection, good long distance signal strength.
- 4251 best long distance capability, but not good for multipath.
- 9095 Winegard quality, but not as good as 4248 in severe multipath.
- 8800 high quality construction, but average performance.
- 3017 Good medium sized UHF/VHF antenna when used with a clear line of
sight.
