I've never used it at that distance, and before I would've bought it for an application of that distance I would've called the company. I have 2 of them at a normal distance of around 15 - 20 feet.

1. This senor works up and down. It has a plunger that drops out of it about 2" to know if the garage door is open. (plunger is up in this picture)2. I now have a second senor not working so well. I'd be very surprised if this will work at 500'. My longest of 3 is only 45'. Maybe they work better if they are not around electrical noise like wifi and power lines.3. Look for something else.

No! Only works about 35'. Also, seller does not respond to questions and warranty. I bought one that had a bad battery. I sent them a message about it an never received an answer.

The one I bought was garbage, didn't work well AT ALL!! Spend quite a bit more on another one, and it will work for that distance

I haven't tried that distance but based upon my experience with the device I would expect that 80 feet would NOT work.

Does work through wall to my garage but not through metal! In plain sight no obstructions it works from over 100 feet!

No it will not work for 30 feet away you would need a 100 feet one to do the trick.

I've never used it more than 100 feet away so I'm not sure. All I can say is it works well between floors. I've been two floors above my mother in our building (an older brownstone) and it works just fine. Otherwise, as the previous responder said, you might have to contact the manufacturer.

Overall a good product but certainly will not work the distance advertised. I didn't do any exact experiments but 500 ft would be my estimate for reliable performance

Only worked about 100 feet. And the device quit working after 6 weeks. Could not get satisfaction from company !

No real idea as 100ft seems a long distance and I did not receive such a long cable. Only cable was a regular cable of approx 10ft. A typing mistake ?

ordered 2 outside antennas neither one performs as advertised claims 125 mile reception. I am 50 to m75 miles from 2 major cities, and I am lucky if I can receive 4 stations had a old indoor antenna in fla and had all major networks. had 40 stations. am very unhappy with the 2 I ordered from amazon.

My unit will not work well at much over 3 feet. I wish I could get another couple feet or so but apparently not.

I bought the same junk. Mine doesn't work either. I am not climbing a 50' tower to bring it down and send back. Amazon has been no help in this matter. I refuse to order any more merchandise from Amazon due to their not caring attitude for long service customers. The antenna is just plastic junk never designed to work properly. Many of us have been fooled.

My original works up to around 35-40 feet and this one does also. Haven't tried it beyond that range. I'm very pleased with this unit and you can't beat the price! Just follow directions carefully during setup and you shouldn't have any problems.

Let me correct my statement.... I just went out and measured. You need at least about 12 feet for it to work.

I have one of the older ones with 100+ft cable. After 50 feet or so, you lose the tension required to keep pushing. I've never used all of the cable because i can't. I'm actually going to get shorter cable.
