Directv SWM SL3 System Not getting Signal on 103

It is all to fragile and sensitive to allow it to bang around and/or be crushed. Even the connectors are critical.

Some argue but I believe the first step is to establish a perfectly plumb mast. Pre-set the Elevation and Tilt and then rotate until you have a peaked signal on the 101. At that point, you are done especially for a short stop. If bored or picky, you can tweak it a little more.

As stated, you can in-perceptively torque the dish and/or arm enough to seriously affect signal. Store it safely, anchor it well for high wind and try to place it so people won't walk or drive into it. I place a couple of the solar yard lights at the base and have added reflective tape to my tripod. Keep the cable flat so they don't trip over that either.

If anyone argues with that, they have no idea what they are talking about. It takes caution and it take precision. Other than that, it does not take much.

Schneid. Excellent advice for all.

As Paul Harvey would say, now for the rest of the story. This should be a final posting unless someone has questions.

After becoming convinced that the LNB was bad, I ordered a new one from Amazon. It came yesterday. This morning, I got everything out here at home and set it up just as I would when off in my 5th wheel.

Here is what I found. 1. The LNB that I had was good and so is the new one. 2. My dish arm was slightly bent downward, too little to see or measure comparing to my house SL3 dish.

I started out making sure the mast was plumb. This appears to be very critical. Then using the AAS, I zeroed in on the 101 with a 95 signal. With the dish tilted 70 degrees (for home) I discovered that I had nothing on the 99 or 103. In trying different things, I discovered that if I tilted the dish back up to 90 (no tilt) I had a weak signal on both the 99 and 103. But, if I tilted it to 70, where it should be, I got nothing. I then tilted it back to 70. At this point, I slipped the LNB out of the arm so that I could move it around by hand. What I found was I could move the LNB up, higher than the arm, and get a good signal on both the 99 and 103. Then, I got myself where I could pull up on the arm as much as I could. I couldn't tell that it moved but it must have. After that, I found that I was now getting the 99 and 103 signals in the mid 80's and still getting 95 on the 101.

So, no problems with the LNB or coax. I was using the same ones today that I was using last week. It was a dish problem all along. I plan to be a lot more careful with my dish putting it and and taking it out of my 5er. I plan to make sure it is as secure as possible while driving. When in the 5er, I plan to keep the LNB and my tripod mast off of the dish.

One thing else I found out last week. I did get the dish to work with very weak signals on both the 99 and 103. The signals on both were in the 20's and 30's. What I found was if the sky was very clear, I could see most everything. But, any clouds could make things much worse. It is much better to start out with good signal numbers. That way if it clouds up or rains, you can still be watching TV.

Thanks for all the help and suggestions.

While the LNB might be at issue, a good working SL3 SWM LNB will give you good signals. Mine is 95-100 on 101 and 85+ on 99 and 103. I still do not understand what the SWM transponder screen means but mine always reads 100.

I am back home now and have been looking into what needs fixed. The LNB and/or the dish itself seem to be the most likely suspects. I took the LNB out and did a Google search on the model number which is SL3S4NR3-01. Man, did I get a good hit. I found a forum on Directv's web site that involved installers complaining last year about this exact LNB. Guess what one of the major problems. Low signal on the 99 and 103. I am going to buy another LNB to replace this one and give it a try.

Wish me luck. For anyone else, if I get a final answer, I will post it for anyone else in the future.

I believe the HD sats are much higher freq than the 101. May be you have damaged cable somewhere?

That sounds right. Really sounds like something is kaput.

Just a thought. Is OP tilted correctly? An AAS can be read wrong. He needs to use the marks on the Slimline. Set as published and move on.

If standing behind the dish, it is rotated clockwise or to the right. I did use the marks on the Slimline to set the tilt. This is after making sure the post is plumb.
