Default Issue with SWM LNB

I attempted to install a SWM SL3S4NR2-14 system and failed. I used a first strike meter, and the signal kept jumping low (both quality and satellite strength indicators) and then disappearing. I took it over to my neighbors Slimline dish, where he has an SL5. His LNB read in the 90's. I put my LNB on his dish and got the same results. It kept jumping to low levels and disappearing. Then I took the SL3 off, put the 5 back on and it worked perfect. I hooked up the SL3 in the house and it showed about the same level of signal, so I assumed the LNB was bad. Now I have another and it shows some level of satellite singal on the meter while not hooked to a dish, but no quality. Is it possible that both LNB's are bad, or am I unaware of something with the SL3S? I tried the replacement I got on an AU9 dish (older 119, 110) and got nothing. The other LNB shows signals in the 90's. Any help appreciated... Also I am powering off the first strike meter, not using in line form the PI.

Thanks!

The Swm LNB needs to be powered from the p21 in order to operate (receive signal) your meter needs to be swm capable. Using a Birddog meter requires a swm splitter hooked to the LNB before you can align the dish or read the signal level.

Using the LNB in the house Will not show u anything.

Thank you for your reply. I did not expect to receive signal inside the house with this or any LNB. I included that information in my post as I was wondering if this could indicate a "BAD" or "Defective" LNB that I may have. I have a 4 port splitter for this device, you're saying it is required even for a bird dog meter?

Thanks,

The LNB (SWM) Needs to be powered from the PI-21 Supply in order to work (receive) Signal.

Example - Connect a rg6 from the PI to your 4 way (red in) or port 1- Rg6 ,Top port out to the LNB - Connect a RG6 to a Spare port of your splitter ( port 2,3 or 4) connect to meter-Then power up your meter. Make sure your Meter can read DirectV SWM Check manual for correct setting.

With the LNB attached to the dish you then can read signal level and aim your dish.

The SL5 You checked did it have 4 RG6 Out puts? If so It's a legacy LNB and does not require DC power. A SWM LNB has ONly One RG6 Output. (NOTE) You may Know that already -Just added for Clarity.
