has anyone had DTV interfere with your garage door opener??

MikeLoew · 10-29-2008, 07:27 PM

Hello all, just put up a new DTV 5 LNB slimline and it is working great. The problem after I installed the new dish my garage door remotes would not work (all 6 of them) the push button remotes will work if I put them about 3" from the antenna. The door works great with the wired wall switch. So I went out and bought a new garage door operator (a different brand by the way) and installed it, and the new one does the same exact thing??? And for your info one of my part times jobs is installing door openers, I have put up about 900 and have never ran into this problem before. The garage door opener tech people said that they have heard of problems with DTV dishs? Moving my dish is not really an option as I only have 1 good spot to put my dish, without tree problems. I am not blaming DTV as of yet but it sure seems like a coincedence. i have also powered down all circuit breakers in my house except the one breaker that powers the door opener to see if any thing could be causing a problem, that also cut power to my Dish LNBs, same results. Any comments?? thanks Mike

If you cut power to the dish and the garage door opener still doesn't work then that proves the DIRECTV dish has nothing to do with it.

Thanks Glenn, I would agree with you, I would think cutting power to the satellite dish would elimanate the dish as the problem. I did try another thing, I took the new garage door openers to a different location 5 miles away and they work pefectly. So the problem is at my house, the only thing left to do is pull the dish down, I really hate to do that as I got it set up perfectly and it was a real bear to install up on top of my chimny on an extention pole to see over trees. As I said the opener problems started the same time I installed the new dish and receiver.

Any other new equipment besides the dish itself? i.e. new tv's, Zinwell multiswitch, signal boosters, etc.

If the ONLY thing new is the dish, it just seems impossible to think it could be the cause. Dishes don't output anything to speak of. They just receive signal, so it's hard to fathom it causing any interference.

Don't shoot me for asking this but have you tried re-learning the garage door opener remotes to the garage door opener unit ?

The day after I installed my new opener the remote control wouldn't work unless I stood in the garage right under the door opener unit. I re-learned the remotes to the opener unit and everything has worked fine ever since.

MikeLoew · 10-30-2008, 04:56 PM

Thanks guys, Jeff, I have no new equipment except the new dish and receiver. And Glen yes I have tried relearning the remotes several times.

knothead · 10-30-2008, 05:23 PM

I had a similar problem with my remotes awhile back. What my problem was, I lived about 4 blocks from my police dept. and it turned out that was the problem. I think they switched freq. because it stopped. Check to see if any commercial or private antennas have been installed lately within a few blocks of you.

MikeLoew · 10-30-2008, 10:37 PM

knothead, didn't any of your neighbors have the same problems? none of my neighbors are.

Jim Bob Jones · 10-31-2008, 05:43 AM

No. Never experienced it and would not expect this to be a DIRECTV issue.

On One side of me is an apt. building and on the other side, they don't have a door opener as well as his neighbor.

Can the garage door and remotes be reprogrammed to a different frequency? Some have that option. If yours do then give it a try.

allensmith · 06-08-2016, 12:29 AM

The DTV dish does not transmit RF there is no transmitter.There is some low level RF energy in the coax coming from the dish to the receiver. If the coax was run close to the openers and is not grounded properly it could maybe interfere . If you unplug the DTV receiver from the wall that should tell you for sure. If it works when the receiver is unplugged it is maybe the DTV but if it still does not work with the receiver unplugged then contact Parkland Locksmith,they are very much efficient.

Sorry to disagee with you but the dishes do emit an RF signal,

The LNB's are RF signal down converters, they take the 12 GHz signals and down convert them to a 1.2 to 2.2 GHz signal, this signal is what is sent down the coax to the switch or receivers, if it leaks out it could cause problems with surrounding RF type equipment.

In some cases we have had to use RG-6 quad shielded coax and a heavy ground wire bonding the system directly to an Earth ground rod.

Most garage door systems run at aroung 300 MHz, if there are any harmonics or spurs in the dish system and they are getting out then there could be a problems.

The only way to tell what is going on is a complete power down of the DTV system, this means powering down all receivers, switches and other components of that system, if the problem goes away it's the DTV system.

If you can beg borrow or otherwise get a hold of an RF spectrum analyzer it will give you an idea on what may be going on.

This is an OLD thread that the OP probably has long forgotten about. However, I do have one thought on the matter. I have a relatively new garage door opener on the house and I've found it is sometimes unresponsive unless I drive right up to the door.

On this unit and on a previous unit on another house, I found that removing about an 1" of coating on the receiver wire that hangs down from the unit makes the opener receive the signal from my remote at a greater distance.

Armstrongsmith · 01-29-2018, 12:48 PM

I was Looking for the best garage Door Openers and some other issues related to their installation and so i found this discussion.I want some suggestions that which will be best and good quality garage door opener? also i saw somewhere that it may start making noises and it may have small range so which will be the quietest and longer range with best in quality.
