I'm upgrading from my 3.5 year old 3lnb disk to the new Slimline dish in a couple of weeks. I've been disappointed at the rain fade issues I've had in the past. Is the new dish more resistant to rain fade?

Yes and no.
It has a larger reflector so for your current channels it should, but the new Ka signals are more susceptible so no.
What are your levels now?
If they are lower than normal, then a better pointed dish will help.

I just had my slimline moved on Saturday and we are now expecting some heavy rain so I am looking forward to see how it preforms but prior to this I was not happy with the rain fade problem to me it is worse than the 18 inch dishes I used.

We've been getting some extreme rain here in Louisiana the past few weeks and the slimline dish I have is virtually impervious to rain fade. However, a swollen cloud that appears just before it rains like crazy will knock out the signal. I'll lose picture and sound for 1-2 minutes and then it starts raining like mad. After raining for 1-2 minutes, the picture and sound return even though it is still raining very heavily.

Wish that was the case here. Mine has been out as long as 45min durning the heavy rain.Does not come back till the rain stops.

I've noticed that my rain fade seems to be worse with the Slimline in comparison to the regular non-hd dish.

I went ahead and left my old dish up and had my Slimline installed near it.

If I have rain that fades out my Slimline, chances are that my bedroom R15 will still be working which is being fed by the old dish.

The rain doesn't need to be "on your head", but between your dish and the SATs.

I'd look at my levels coming from the slimline. My dish has lost signal, but only in extremely heavy rain/hail storms.
HD locals [Ka] will fade early, but I can't think your smaller dish would work better [if the slimline is adjusted correctly].

as old school said .. rain doesnt have to be head on ... as a matter of fact .. you could be getting a sunburn at the same time .. reason ... that big ole T storm off to the "south" (inline with the sats) is the real problem .... for example .... you see rain .. maybe 1-3 thousand feet of it ... while the water in the clouds can be 30 or more thousand feet

I am curious about this.

Unfortunately it hasn't rained since I got the dish installed on the 6th.

Hopefully tonight. Grass is turning brown and trees are starting to loose leaves. It's not supposed to be like this in WI in July :mad:

Thanks for the reply. I agree with you totally...and to be honest, I was probably watching HD local when I experienced the rain fade.

I will be checking the levels non-the-less though.

My experience is that Ku channels (essentially everything but HD locals) are less susceptible to rain fade with the Slimline dish than with the 3 slot dish.

Ka channels (HD locals) are slightly more susceptible to rain fade than everything else was on the 3 slot dish.

This jibes with the laws of physics in general.

The original Ku channels now have a bigger reflector to bounce off of and therefore have more gain than they had before. Therefore, they are less susceptible to fade.

The Ka band, in general, is more susceptible to fade than the Ku band. So, it is what it is.

I've had my slimline dish for a few months now and hardly experience any rain fade at all. We've continued watching TV through some pretty heavy storms and no problems. As a matter of fact, a problem tree with the old 3LNB dish caused problems , but I now have no problems whatsoever (with or without leaves), all thanks to the AU9S dish.

I had a bad case of rain fade(20 min) a few days ago during a really bad thunderstorm. I lost signal on all satellites except 119. I have a slimline. Any ideas why I would have just that one vs 101 sat? By the way my normal signal strengths on all sats are 98 with hr20. I still have 98 signal strength on the sats.

The storm came from the east and wasn't that far west of you.
