    Unless they make a future satellite on 101 spotbeam only, there is no room for every single market with SD locals on 101 to move their HD locals off of KA.

    NYC and Philly share 3 transponders on the same beam on 101 for all their SD locals. While for HD they don't share any transponders, NYC has 2 transponders (the big 4 are Conus remap of the DNS feeds, while WEDW comes from a remap of WEDH from Hartford), and Philly has 3 transponders, and that's before you have to deal with any SD only locals or ones that might go HD between now and then. (i.e. Just this past week WBPH in the Philly DMA converted their OTA signal to HD and will eventually have their HD feed added because they chose must carry instead of retrans consent where they would have had to negotiate a deal for carriage) When you take into account all the SD only locals both markets have, they would need at least 6 transponders on 101.

    Then you have to deal with the needs of the next big cluster over that shares spotbeams and transponders on 101, Washington/Baltimore/Harrisburg since they would need their own set of spotbeam transponders for each of their locals that don't overlap Philly/NYC. (As well as Richmond which, while it doesn't have SD locals on 101, it shares a HD transponder with DC)

    He seriously said the dish shouldn't be installed 'low'?? Unless line of site or a pole mount that wasn't stable was the issue, moving it from 'close to
    the ground' to the top of your house is what, 15 to 20 feet?? Considering the satellite is around 23,000 miles away, that 20' isn't going to make any difference.

    Back to the OPs question about rain fade, as a single data point here in North Carolina, north of Charlotte, I have to say rain fade is worse in the last 5 or so years. More intense storms, slowly moving storms.

    I've had RF when it wasn't raining at my house, but a small cell southwest of me sits for a while. . . 3 or 4 hours! You have to realize it's not the rain on the dish but the rain that the dish is looking through - here it's fairly close to 45 degrees so a thunderstorm that's 30,000 feet high (~5.5 miles) a mile away presents a lot of rain for the dish to look through.

    In the last 2-3 years, I've seen rain rates over 10 inches per hour (short duration) or 6-8 inches accumulated in 2 hours or less. We're currently ~8 inches behind for the year but that could change with one small cell. (or a tropical cell)

    I guess because we haven't heard anything about it for awhile.

    It is raindrops in clouds that cause all the fade. So it doesn't actually need to be raining for you to have rain fade.

    True. I have it rain fade more often when it is not raining on my house when the heavy cloud is south west of me.

    You reminded me that it start breaking up with just thick clouds.

    The other day I had 1.5 inches of rain fall in about 45 minutes. My TV did not go out during the downpour.
    Then that same cloud moved to the southwest and the TV was out for about 20 minutes.

    If you live in Kansas, you should have a smartphone app like "Storm" from intellicast to help with severe weather/tornado warning. You will have a radar picture that updates every 5 minutes. If you see a nearby or overhead red radar echo in the direction your dish points, you can expect rain fade. You can be in fairly heavy rain, but if the main (red) part of the cell is north of you, you probably wont lose the signal.

    I'm just north of KC and rain fade this year has happened with virtually every rain storm we've had this summer. I thought that having my dish moved to the roof after a couple of trees started blocking my line of sight would help, but it hasn't. By the time I switch over to SD it has already started to fade there too. The weird thing is, my HR34 will invariably go out before the HR20 which makes no sense to me!

    The only reason having it low would be a problem if there was something blocking the line of sight. And the angle of the signal is actually higher than where the dish appears to be pointed. This is how I had mine mounted when I was in CA. Looking at it, you would think the fence was in the way, but it wasn't in the signal path, They are actually a little farther from the fence then they appear. But the point is the height should not be an issue (barring obstructions). My current dish is pole mounted with the dish at 6ft. It's been that way for 11 years now.

    Anyway, as to rain fade here, I had noticed that I had been getting lower signal levels than I had before even on a clear day. Some sats like the 92 were in the mid 80s. DircTV rolled a truck and he aligned as best he could but it did not change. Unfortunately he did not come out on a clear day. So I bought a new LNB on ebay and the signals went back up to the low 90s for a few years. But once again they were starting to drop back down and I would get a 771 if there was just a heavy cloud. But after my HR54 install a few days ago and another new LNB (the 21 tuner RB version) even the 92 sats are at like 95-96. For me, I think the TX sun/heat just cooks them after a few years.

    He did say it. I never really believe them, but it's not really an argument you're going to win either.

    It's good to know that it's more than just rain hitting your dish.

    This is good information to know.

    I'll have to check that out the next time I see issues.

    There's nothing on the south side of my house besides some residential power lines. There's a farm adjacent, so they weren't avoiding obstructions.

    Sunny day today and signals aren't much better, 99 is in the mid 80s to low 90s.. So I may need to tweak alignment to get that (back?) to all 90s.

    Low in a southern state would have less consequences than low in a northern state (especially the northeast). My dish is low ... about 15 inches off of the ground. It makes it easy to maintain and keep the snow off of (it is in a place where the snow doesn't drift that high). But being in a northern state, the elevation is low enough that I can cause a signal outage by walking in front of the dish.

    The former owner of my home had a low mounted dish that was bent up from where he kept hitting it with his mower. One can do the same damage to a pole mounted dish as well (or to the pole itself if hit hard enough). I went for a better location where the dish would not physically be hit but it is still close enough to the ground that I can't walk too close to it when working in the yard.
