AU9 Weird installation question

[wcr-atl]

So, I just installed a new AU9 Slimline dish at my lake house and connected it to an H20 receiver (no B-Band converter).

On the first day I got the dish aligned and was getting 90+ on all transponders. Watched TV all day - no problems. Ok, maybe an occasional quick 771 when switching channels but I was getting all of my channels in beautiful HD.

When I awoke this morning and switched on the TV, no picture. No 771 - searching for satellite.

I checked my signal meters and saw a curious behavior - on the 101 transponder 1 my signal would peak at 90+ for 15-20 seconds and goto zerio for a while. Peak and disappear.

Also - when I look now at all my transponders it appears I always get a signal on the 101 satellite on transponders 1,3,8 (and a couple of others, but always 1,3,8 and zeros on almost all of the others).

Any suggestions? I checked my cable (way less than 100 feet) and it's RG6.

Help?

Did all bolts get locked down, looks like the dish have shifted.

Also no BBC???

no b-band??? and you got HD..

did you install a SWM lnb?

trees blowing around in the area?

Yes - its a SWM and I definitely got HD.

Problem is that I tried probably 20 times to realign the dish with the same result every time. It worked flawlessly for half a day.

Just saw that a power inserter was *required* and I definitely don't have that. Would not having one of those cause similar problems?

Why would it have worked for a while?

Ordered one just in case....

Yeah, you have to have a power inserter, for any SWM system. I believe that you need the model PI-21.

Sounds like the SWMline was managing to just barely run on the voltage sent up the line from the receiver. As you found out, that's not strong enough. The off-and-on was probably from some kind of overload protection circuit kicking in.

Hopefully, that also protected the receiver from damage to its internal components.
