I have had a slimline and WB68 operational on the railing of a deck for 3 years now. Recently some warping of the mount and some tree growth have
caused lower signal strengths on 95 & 103. So, I bought a new slimline and WB68 and pole mounted it some 80 feet away where I have an unobstructed view of the satellites and easy access to all alingment adjustments. Before switching all my receivers to the new dish, I connected only one H-20 for test purposed. Signal levels were significantly higher.... low 90's and high 80's on 95a and 103b. But, 103B is flaky. Sometimes I get great signal strengths on 103b, sometimes all zeros, and sometimes zeros on the odd transponders. What do you think might be causing these variable results on 103b?
The post shown below shows some ideas, but what concerns me is that the
problem is not constant, and varies as indicated above. When I first aligned the new dish, I dragged a receiver out to the dish and had a 12' piece of
RG6 directly connected from an lnb, thru a BBC to the receiver. The signal strengths were high and did not vary on 103b.
Check the dish
The easiest way to eliminate the dish as the problem is to swap cables as they enter the switch from the dish. There are two cables going into ports labeled ~13v/22KHz and ~18V/22KHz. If you swap them the test channel failures should switch and the signal strengths on the evens/odds should reverse. If so, bad cable, good dish. Check the cable ends and look for a bad spot.
If swapping the cables had no effect, bad dish. Call for replacement.
Bad Cable
But which one? If the even transponders on satellite 103°(b) are zero, the cable plugged into the switch port ~18V/KHz is bad. Check the connectors at both ends and perhaps replace the whole cable.
If the odd transponders are zero, the cable plugged into ~13V/22KHz is bad.[/QUOTE]
