Power Inserter needed for SWM tripod antenna

Yes, indeedy. The PI must be between the receiver and the SWM, not between the SWM and the antenna.

Excellent.

Finally got it to work. Connection as follows:
SlimLine antenna with SL3S (1 eyeball) LNB to Splitter SWM 4 way IN; OUT to Power Inserter Power to SWM port to Power Inserter Signal to IRD (Sat Receiver) Sat 1.
After connecting this way, I no longer got the screen message: CANNOT DECTECT SWM, but I did get a message to not connect B Band Converters. I still hadn't aimed the dish properly, but as soon as I did, the signal meter on the Sat Receiver starting showing a signal. Fined tuned the signal by making small adjustments on the dish azimuth and elevation. Locked in all satellites. In my case those satellites are:
99(c); 101; 103(ca) and 103(cb). Got HD on all channels I subscribe as well as locals and national networks (east).
All is good.

There is a plethora of wiring diagrams online.. you may wish to avail yourself of that.

Choice two. Make sure the receiver is configured to accept swm ..that's in the setup menu.

Mine is lnb to splitter where splitter has input from pi. Boy it really takes patience to type this on a phone.

How are you aiming it?

I have connected everything together and get the following message on the DTV receiver: CANNOT DECTECT SWM. Here's my connections:
Slimline antenna with new SL3S (single eyeball) LNB to Power Inserter to Splitter SWM 4 way to DTV model H24/100. This receiver works on my house dish, but not on Slimline dish mounted on the tripod. I've tried with and without the Splitter. Am I getting the message because: 1. the dish hasn't been pointed at the satellite (101) properly or 2. I have something not working in the connections or I've connect something wrong/

Question, Why did you state the subject as "Power Inserter needed for SWM tripod antenna", then?
You may it sound like you needed a PI from your SWM system. Just asking.

My DRV tech sold me aPI AND A 4 way splitter that had an output to the LNB.
The PI connected to the splitter.

sounds fine.
