    Nah dude! That was all I had on hand at the time.

    When we had the small KTI single LNB dish, rain fade became a real major problem. So much of a problem that a real light rain caused signal loss.
    I Googled "rain fade" before I found this wonderful site and read up on the problem.

    I would think RainX or any type of polish that would help shed water quickly would work.

    I am going to give it a try do you just spray it on or do you ruib it in? Light rain does not seem to be a problem but moderate to heavey seems to be. I use to have a 3 dish set up and never had a problem like I do now and eventually may be a deal killer for me once football starts and I have rain fade problems it will not sit well with me.

    It is barely even raining here (the windows are dry) and I'm experiencing rain fade.

    I have an H20.

    Sat 110 is low 30s. Both 99s are all NA. 103 is mid 20s to low 30s (or 0). The other 103 is NA. 101 is mostly mid to upper 40s with a few in the mid 60s. 119 is all 0.

    Where do I locate these bigger dishes?

    With your location, there must be another reason. How long are your coax runs?
    I've had rain fade and know how hard it must be raining or hailing and it's quite a lot.
    So on a "good day" what are your SAT transponder levels?
    What's your line of sight? Any trees?
    You just shouldn't need to use anything bigger than an AT-9 or AU-9 if you setup is done correctly [even with long cable runs, which might need some amps to make up for the loss].

    On a good day... 70s on 101. I don't remember on the other sats.

    I'm going to guess that the line is 30 - 40 feet. I go through a pair of female-female connectors.

    It is raining harder now, but I can still have 3/4 mile visibility.

    The nearest trees are 100' away and are under 45*, perhaps under 30*.

    On 101, normally a non-zero min of 16, max of 98, average of 67, and stdev of 14.

    Your dish needs to be better aligned to start with. Your levels should be in the 90s.
    Your cable runs aren't too long [200'].
    Your female barrels should be waterproofed if they are exposed to the wet.
    here are some of my levels:

    All of the stuff I did is inside. The installer mounted, aligned, etc. the outside. Actually, there is another female block outside, but that one has rubber bushing weatherproofing.

    I thought that with the H20 it was normal to be 20 less than what the signal really was.

    The first column is my friend 2' south of me. The second column is mine. Both had "professional" installation.

    The software for the H20 was recently update to display a more accurate levels.
    For the past year, the readings have been low do to the software.
    Some Transponders will read low because they are spot beams that point somewhere else, but the national beams should agree if the software on your H20 has been updated.
    Check what version of software you have [setup/info screen] and then maybe it will show if your dish alignment is good or not.
    Because you're having rain fade so easily, I don't think it is.

    That's last years software, so yes it will read lower.
    Do you have any other receivers?

    This can be a problem for two reasons:

    1. Insertion loss; any break in the cable results in some signal loss
    2. High frequency attenuation if your couplers aren't capable of >2GHz

    Number one will attack channels across the board while number 2 will attack even polarity channels more.

    I had a D10, but I just swapped it out with a Samsung HD unit (grandma couldn't learn the Samsung's remote). It reads 10 - 15 or so higher.

    How do I get the software upgrade?

    I'm not sure of the insertion loss or frequency range of the connectors I have. I'm actually not sure where I got them now to double check.

    Right now it would be through the CE software forum.

    So that means that the firmware that I have reads 20 or so less than what it really is?

    So that means that my signals are normally in the acceptable range, but I am experiencing large amounts of rain fade?

    Yes the firm/software does read low.
    The rain fade shouldn't be "large" amounts nor should your reading be as low as you posted today.
    When I have rain fade it lasts for five min maybe in the heaviest storms.

    So then should I rent one of those signal meters and follow the steps for aligning the 5 LNB antenna that I saw in a DirecTV video? If I were to do that, I'd probably purchase 2 other 5 LNB dishes to upgrade other sites and tune some other dishes at the same time.

    Well I can't say what you "should do", but I can see the sense to it.
    You really shouldn't need a larger dish unless you're in Alaska, Hawaii, or somewhere outside of the US.
    If you coax cables are in good condition, it really does point to the dish as being your problem. IMO
