Default Direct TV when it RAINS??

Does anyone have as much trouble as I do with direct tv when it rains, I can understand a very heavy storm but almost anytime we get rain I loose my direct tv. It seems the local channels will work ok but even they freeze and the premimum channels go out completely.

I reset my tv this am and can not watch ESPN or other channels in my den, this is where we have the high def reciever, but the one in our bedroom picks up most channels fine but still no ESPN 2.

I have talked with others and that live in the same area as I do and nobody seems to have the same trouble as we do.

Could it be the location of our dish.

I am going to call them AGAIN this am, this is getting old in a hurry.

Never had this much problem till we changed to the high def back last fall

check the mounting of your dish. You could be getting rainwater on the receiver portion of the dish.

if you have a HD system - how many "eyeballs" does the thing have - the LNB that points back at the dish. Are they centered on the arm or offset?

No matter what you have I am confident it needs a realignment and probably some rewiring, but want to know so when you call you can talk in technical terms.

How many service calls have you had?

I was told that the reason why you lose signal when it rains is because the rain on the dish blocks the signal between the dish and the LNB. I was told that if you cover the distance between the dish and the LNB with something to keep the rain off of the dish, it wont lose signal.
My stepdad put rain-x on his dish and it seems to be working fine in the rain. You might want to try that and if it doesnt work then try to cover it somehow with out blocking the LNB.

Most definetly an alingment issue, My Sat TV would not work in the rain 4 days after I had it installed, I went on the roof and found the "tech" had not even tightend the clamp on the mounting pole!! after explaining to customer support I was not going to pay to have it re-aligned the tech came back and re set it. I marked the X and Y axis along with the pole clamps with a paint pen and it works all the time now. Good luck!

I had similar problems years ago (but did not have HD). It made me insane that I couldn't watch TV when I most wanted to (bad weather), and I switched back to Comcast. Can't say I'm thrilled with Comcast, but I don't have your issue anymore. I really wish there was more competition in this space. My town doesn't offer Fios, so it's either DirectTV (which I don't want), or Comcast.

HD systems have many other opportunities for signal failure besides the alignment and with the regular def set working it is telling me it is not a systemic issue, rather (mostly) an issue with the HD wiring and possibly the alignment, depending on what dish is used (varies by market and installation type)


Biggest contributors are:

Improper grounding block (1 ghz -v- 3 ghz)
No grounding block (does not allow static electricity to discharge)
Impromper fitting (blocks higher freq's)
Fitting not made correctly (suck out - yes that's the technical term)
Improper coax (steel clad or RG59 - blocks higher freq's)
damaged or improperly attached coax (crushed dielectric blocks higer freq's)


The reqular def systems push up to 1250 mhz, HD up to 2250 - most of the above cause blockage which allows the reg def to work but not the HD stuff. Can be intermittent as well, especially if not grounded properly.

tprice - I had an identical problem with my DTV dish. Even something as small as a light misting rain would take out the signal on the premium channels. It was traced down to a f-connector where the coax meets the dish pigtails. Some moisture had gotten in there and the voltage on the line accelerated the corrosion. That thing was taped as tight as a hat band but it was corroded beyond belief in a matter of months.

It's a pain in the ass but you have to open up all f connectors and inspect them. Good luck -- let us know.

A normal rain should not block signal.

I just went through this. Look carefully before you pay to have the dish re-aimed. My service was messed-up during almost any extended rainfall. Turned out that tree branches that normally were out of the way hung down lower once they got wet, blocking the signal. I went out in the rain and noticed the possibility then proved it by throwing a volleyball at the branches, knocking the water off them, and having my wife yell out the window when picture came back . Tree got a good haircut the next weekend.

Try the Rain-X too.

I lose my HD channels often in the rain, so I am forced to switch to the same station in non HD which normally still come in unless the rain / cloud cover is really bad. I laugh at the DTV commercials that talk about working during and after a hurricane, because the first thing we lose in a hurricane is our DTV signal.

Thanks for all the help, this does get aggrevating when you are wanting to watch something and the tv goes out but after talking with others I am loosing the signal when they are not.

My dish is located behind our house shooting over the top of the house. In our front yard is are 2 large trees that are close to the house and higher than the house(2 story house). I can not help but think these trees are the problem but have nothing else to base that on other than my own redneck ideas

Based on your description, I tend to agree. Could it be that the rain (water weight) is changing the characteristics of the tree's branches and affecting signal?

and look for hidden ones in the entire run. Some techs cut line short and then hide a splice. Found this in Jackson MS yesterday. Notice the corner cap for the siding - that is where this was stuffed. The two top fittings are old and not approved for our installations.

not if shooting over the top of the tree - added weight would actually help. This would affect if shooting under the tree.

Again, depending on the dish used will determine which sats the thing is looking at.

True. He said he was shooting over the house and the trees were higher than the house so I thought shooting under (or through?) the branches was a possibility.

possible. Also remember that the angle of the incoming beam is higher than the tilt setting on the actual dish. It comes in high then bounces off the reflector to the LNB.

Had an old guy tell me we set his wrong because he got his protractor out...



Typically it is low frequency items between the LNB and the reciever OR the dish was not properly "dithered" (fine tuned) The signal on the HD beam is waaaay smaller than the reg def. Picture regular def as a silver dollar size and the HD as a penny, but half the size of a penny. If not dithered perfectly, the beam is lost very quickly with minimal rain (or even heavy clouds).

Those two are main causes, dithering usuall taken care of on first service call but usually the service tech will not touch the whole job and will miss the underlying issues.

Here's an old ground block that caused 3 service calls because the tech did not look at the entire job.






Here is another job that had the correct ground block, but the old fittings were sucked out causing issues. Three of the four fitting were not approved, the top right was the really old one causing the issue. btw "suck out" is when the line expands and contracts repeatedly causing it to eventually pull away from the fitting, losing contact. Extreme heat during the day followed by cooler temps at night can cause a nighttime issue when the center dielectric (the white core) contracts.

I just got DTV a few months ago and that was a concern of mine. But its not to bad. Only in heavy rain and usually only for a short time. The longest it was out was for 20 mins. But what we do is record all our shows on the DVR so we can zoom through the commercials. When they are recorded you can watch them no matter what.

I am having a small issue though. I get these ghost lines moving from the bottom of the screen to the top. It seems much worse during and days after it rains. I put the TV on cable (I have both) and I don't see the lines. And its only on the TV with the HD DVR.
