Rain Fade

[cditty]

I have Dish and Direct for different reasons... Can someone explain to me why Dish handles Rain Fade so much better? I can lose Direct for 30 minutes (and I have excellent signal), but maybe not lose Dish at all or it just go in and out a few times during that time frame. I am Eastern Arc on Dish.

Ku vs. Ka

Directv uses Ka satellites for High Definition broadcasts & Ku off 101 for SD broadcasts. DISH only uses Ku for their broadcasts. Ka is more prone to rain fade because the wave length of Ka is smaller.

the big boys in the satellite business (Intelsat) say there are quite a few variables to look at but all things being equal KU is the gold standard

Well, I bet the TS would disagree with the big boys.

Google for some interesting studies on KA link budgets. The KA 1/2 wavelength is the size of a large raindrop (7mm approx.) and can easily be attenuated or eliminated during any weather event with sheeting or dense rainfall. KA has had significant distribution challenges in regions with significant rain and cloud cover.

C-band is the gold standard, with the highest link budget margins then next is KU then KA. C-band signals will barely be lower and won't drop out during even the most extreme weather. Of course C-band is no longer the preferred Direct To Home distribution method, but it is still the primary way that most subscription services get their general distribution channels from the programmers.

I am glad I went with DISH years ago. Not only I think the equipment is better, I very rarely have rain fade issues. When I do it is just for a few seconds.

I had 0 rain fade yesterday, and we got over 6" of rain here. Of course, I have a "custom rain buster" setup of three 30" Winegard antennas each pointed at one bird (110,119,129).

Nice setup.

Nice setup.

I was originally on EA here, and for some reason on the 1000.2 dish, you can just get high 40s low 50s in NW Ala on 61.5. I decided to swap to WA myself, and while I was at it I just got those 30" Winegards.

Is it possible that the Dish is aligned better than the DTV? That's where I would start.

Can I do 2- 30 inch winegards on my Eastern arc, 61.5, 72.7? I already have a Dpp44 in the mix

Yeah, just get some DPP single LNBFs and run those to the DPP-44, this is the dish I use "Winegard DS 2177 30" Satellite Dish with D Shaped tube for Dish Network Support" got them from Solid Signal.

Have you ever had DirecTV? He is right, with that Ka band, a shower can knock it out.

No, but I work on my brothers, and we lose signal at the exact same time for the same period.

I'd give my eyeteeth for some extended rain fade here in dried up California!

Could be a lot of things, the dish could need a check on the alignment, but you are in AZ, the OP is in Louisiana, I am located in Alabama, so the signal could be slightly lower farther east. Also, there is a huge difference in weather. High humidity, lots of rain in Louisiana and here in Alabama too. In AZ you are in a drier climate than the humid sub-tropical climate of the southeast.

Wish I could send you some, I bet we have had 10" or more in the last week here.

Actually, Directvs Slimline IMO is better the Dish networks Eastern Arc against rain fade.
Rain fade with the Slimline is not that bad, Certainly it takes more then a Shower to knock it out.
Ive had Directv from 2007---2013.
The 1000.2EA is far worse!!!!!!

I have ea and 2 days ago I had the first extended length of rain fade. It was probably for 20 minutes. It was a lot of rain that I hadn't seen here before. I turned on the FTA dish and started watching on my 1.2 dish. I was surprised 103 came in like always.
