    Updated: During a storm, it REALLY helps!
    http://www.dbstalk.com/showthread.php?p=2816449#post2816449

    Just a quick addition...After the signal finally went out on the 1M dish, we got 60mph wind gusts, pea size hail, and the power went out for an hour, so I dont think any dish could pick up sat signals through hail. Im gonna keep the 1M, and take down the slimline. Even at the worst of the storm (before the power went out), it was actually trying to pick up 101, bouncing between 0 and 20.

    OK, since it was 70 degrees today, and I got tired of watching football, what a better day to modify the hillbilly 1M Directv dish... I removed the reflector, and mounted it on my old AT9 mount, thus allowing for fine tuning. Propped it up on a temporary pole mount in the back yard, and played around. This is what I came up with.

    NEED HELP - If someone could look at the close up of the LNB, you will see it is being held on the FTA LNB mount (plastic) with two small bolts, and is "pressure fit" to be held down. Does anyone have any suggestions on how to make this mount more permanant? Its my last step before I can use this permanently. The catch is the width of the LNB throat is wider than the width of the bolt pattern, so I cant just clamp it on there (the bolts are actually somewhat sideways.

    Once I solve this issue, Im gonna have me some HD during thunderstorms this spring.

    Get a piece of aluminum bar stock from Home Depot or Lowes, cut a piece long enough to extend past the width of the LNB throat. Drill holes and attach to the existing mount. You can then use another piece of the same stock to fashion a clamp over the LNB throat.

    That is an idea. Since I cannot raise the LNB throat much without putting the LNB out of the dishes focal point, it would have to be pretty thin. Ill check out what they have.

    Trying to watch the NFC Championship game...

    Well, first storm line since I got this permanently installed....

    DirecTv 1M dish crapped out when the red on the radar hit. - Switched to Tivo OTA

    Tivo OTA pixellating with every lightning flash - Switched to HD Homerun OTA on better antenna....local Fox station broke in with storm coverage, preempting the NFC playoffs.

    Switched to C band (10 footer) and watching the game from Fox Springfield, and even IT is occasionally pixellating with lightning flashes.

    Energy of atmospheric lightnings is way off what the all sat could produce. You can't beat them on your TV screen.
    Visiting the stadium is only an option. ;)

    Just an update now that the rainy season is here...

    KA sucks. Even with the 1M dish, I am out of signal on the HD channels. Radar map attached. At the same time, I have high 80's, and low 90's on KU. I still think switching to KA was a bad mistake.

    Yea, if I could afford the taxes, I would still be in SW Wisconsin. At least there you can heat the dish :)

    im not sure if it would knock you way out of the focal point but why couldnt you just use the entire kaku setup. it looks like you are already using the azel, so why not use the arm too that way your lnb is secure. and just use your dish to that instead of the slimline dish .. have no idea if that would work just wondering if you already tried that .....

    I tried that, the focal point of the 1M is further away from the dish than the slimline. I get great signals (all 100's on KU, 95-99 on KA) when its not storming. I dont think even adding another .2 meters (Alaska Hawaii 1.2M dish) would significantly help KA. Its just to damn close to the same wavelength size as the raindrops and hail in the storm clouds.

    Ive added a strap across the top of the lnb throat to bolt it to the arm, so it doesnt move a lick now.

    Has anybody tried the actual 1.2m Alaska/Hawaii dish in the lower 48 states (Especially the Northern states)? Wondering what kind of signals they get, and how much it helps with rain fade.

    On guy tried one temporarily on his deck, but dont know what the results over the long term would have been. Sure would be nice if someone would pipe in that actually uses one. Since the gain of the dish is known, you could use the satellite footprint maps and calculate adding that dishes gain to the Slimlines, and then go into the footprint toward the boresite, and find an area with the same signal level on the map, and know the dish would perform at your location as well as a slimline at that other location.

    On KU, its an amazing jump in signal. KA should be equally if not more increased, but the KA signal is much more susceptible to being absorbed/refracted by the atmosphere.

    Little conflicted on getting one. I can have one sent right now for $654.01, but I know that if anything goes wrong with it, it's MY problem, not Directv's. Also, if they change their satellite scheme, I'm going to be swapping stuff out too.

    What issues are you having that you require more gain?

    Just rain fade in general. Like to "Beef Up" the signal strength if possible (I realize, even a 30 foot dish would experience rain fade).

    Build you a 1M. The dish cost me like $25, the LNB was about $45, and I used a scrounged old AT9 mount, which you should be able to get from an installer swapping out for a slimline. Mounting the LNB securely was the only real problem, and the suggestions on here were great. I can say, I dont think ive lost KU since I put it up. The rain fade on KA is about 1/2 as long as it was before, and minor storms no longer cause any fade.

    Makes a fun weekend project.

    Honestly, since I only record HD, not really interested in Ku signals (Other than Friday nights around 11 PM of course ;) ). REALLY like the help the Ka signals though.

    Guys do your math for the area differences of the reflectors.
    Your gain is going to be less than 10 dB, maybe less than 6 dB, with the 1 or 1.2 meter reflector, and the rainfade is on the order of 30 dB, so I tend to think you're pissing up a rope.
    Now a 10 meter reflector, well.... :lol:
