A few things here to discuss:

Mogulman: Your numbers are good enough although they could be improved slightly. The tilt is off as 119 should be about 95 plus a half turn or so on the fine adjustments to get 103c at 95s and 99 in the 85 to 95 range. However, you have it about as good as it gets as far as rain fade is concerned, that is, the additional adjustments would not materially effect onset and duration of rain fades.

cavman: Rain fade is a fact of nature and until some basic Laws of Physics are repealed will always occur. The real culprit in the rain fade equation is the thunderhead, filled with moisture, boiling up 50-60k feet to the SouthWest. A heavy rain can cause some attenuation, but its all the water in the thunderhead that does most of the damage. It is possible to have no rain at your house, but a thunderstorm passing to the south of your location will take out the signal. Conversely, it can be raining cats and dogs at your house, a real gully washer, but you will not lose signal.

The 'alignment procedure' you described by the 'expert installer' gave me a good chuckle. Given the same receiver, readings in the 80s are not better than readings in the 90s - no way! Now, it is entirely possible there were other issues (coax, connectors, etc.) that could be effected by weather and lumped in the broad category of 'rain fade' that could have been causing your problems. These could have been fixed as the 'expert' made changes to your system.

The antenna is either aligned on the satellite or it's not. The expressions "not properly locked in" and "receiving on the side of the signal" as reportedly used by your 'expert' would require some explanation for what he really meant for me to comment on what he was really doing. But on their face, they are nonsense terms when used in connection of aligning a DTV dish.

I don't wish rain fade on anyone and I would certainly like for you to never experience that phenomena again. But physics says you will, unfortunately. I suspect the recent rain event, when you did not lose reception, was a local thundershower almost directly overhead and the southwestern sky was clear or only partly cloudy.

90+ signal being a false positive and catching the edge of the signal? Signal in the 80's is better now than the 90's? Never heard this before? Anybody care to elaborate?


In order to "Peak" the Ka band doesn't the Ku band go "off-peak" a little? I thought I read this in the install docs back when the sirdecar dish came out. It made dish pointing more of a science than than the old round dishes.

So smaller numbers on the Ku would make sense if the Ka were truly "peaked".

In our area in clear weather we will get 90's+ on most sats.

Right - but which one? - lol. You can have a really good signal on one and still be bad on another.

I've noticed that since the new satellite went into service that we've been getting more skips/drop outs and rain fade is worse. Probably coincidence...maybe..

Anyway.. I have an HR20 and an H21 hooked up to a Slimline dish. It was installed about 2 years ago as an upgrade from SD service.

I've attached signal strengths from the 103 sats.

Is this something that can be fixed by re-aiming my dish. If so... is there anyway for me to get this done without paying for it?

I lost my job a few weeks ago.. I can't really afford to pay to have someone make this better. I've been contemplating getting rid of Directv to save money, and if this is going to cost something, then that might make my decision for me. I'll either go to bundled cable (with my internet) or just do OTA with my HTPC.

I'm kind of handy myself, but I've tried aiming my dish (older dish) a few times in the past without really making anything better.

BTW.. I've had service for about 8 years. I'm not under contract right now.

Any suggestions?

You didn't even provide anything to validate your recommendation. I say, stick to the HD Lite forum, with the provider you obviously love.
HR34-700, HR22-100
