    I was at Sam's listening to the Directv salesman sales pitch. He said, "that the new reflector part of the dish, with the white writing, is better then the old once". With the new reflector their no more rain fade. I was wondering is the salesman correct or is this just B.S.

    BS, rain fade is when the signal is block by high thick clouds. If you have a strong signal then rain fade is minimal.

    Same dish, different writing on it.

    ..and remember the guy at Sams does not work for DirecTV, he's a reseller and I would not believe anything he told me.

    With the older sats, there were people that bought a larger dish (improved signal strength) to reduce rain fade. Dish reflectivity improvements would serve the same purpose. There was a patent back in 2013 (WO 2013108225 A1) to improve the reflectivity that would cover the higher frequencies. So, while it is most likely just sales talk, there is the possibility that improving the reflectivity of the dish without incurring increased costs would benefit them by reducing customer complaints and an improved customer experience in rainy areas. Without knowing how much improvement, or the effective increase in reception, it is all just hype. Intense thunderstorms would probably still result in loss of signal unless the improvement is really huge, which is unlikely.

    well, if you did read the patent then you should know it's not applicable to DTV steel reflectors

    That is what I thought.

    You hit it on the head with this statement, key word HUGE. How to eliminate rain fade :) :)

    Even those dishes suffer rain fade - that's why Directv has so-called 'diversity' sites for all its uplink locations, so that if they are under some extremely heavy rain the uplinks won't be interrupted.

    Ka band can have 100 db or more of attenuation during the heaviest downpours. 100 db of attenuation is around 10 billion times weaker than the original signal, while if you double the dish diameter you only get a 6 db increase or 4x more powerful signal. That's what you're up against.

    For Directv's HD, you have about 10-12 db of margin in most areas of the US with a properly aimed dish. Lose more signal than that, and your screen goes black.

    "See, the color difference of the reflector increases the signal by +5 db, and the writing has a special metal in it that helps amplify the the signal integeraty. And also the 0.001 MM offset helps too with this revoulutanry design"
    Hmmmm, I could be a sails man ;)
