I went through this several years ago and went with the US Automatic Sentry double swing opener. Bought it through Amazon. Its a great opener.

Good advice, have 3 gates with these and after 11 years no problems . Only maintenance was to replace the battery

"Back yard"

So it is on a concrete driveway?

Circling back on this thread to provide an update.

I went with the Ghost Controls opener. We installed two weeks ago and it works great! Easy easy set up and adjustments. Programming the remotes and keypad was also very easy. Instead of mounting the panel to the fence, we made a box for the marine battery and control panel with the solar panel attached to the top, making it all a pretty clean and weatherproof install. We also fabricated a stop out of bar stock to keep the gate from swinging any in heavy wind.

Project took 4 or 5 hours to complete, but most of that was fabricating the stop and building a bracket for the actuator attaching to the gate itself. We did find that the antenna was missing when shipped, so range was very short. I called Ghost Controls and they Rush shipped a replacement for no charge and we had it within a couple of days. Now the range is probably 250' or so.

We'll see if any problems going forward, but so far, so good.

I have a commercial Lift Master gate opener that is on a heavy duty 18ft bull gate at my place. It is on solar... It is supposed to be an upper end model that I had professionally installed and glad I did with the computer hookup inside that thing.
It has worked good “for the most part”. After first being installed about 2 1/2 years ago, it was draining the battery. Company rep that installed it said it was hooked up wrong... Worked good “for the most part”. Had a couple more issues with occasionally the battery being dead...
Now, yesterday morning, battery was dead again (second time in two weeks). Called the owner of the company and he came right out. He was puzzled so he called Lift Master. After diagnostic tests, they said it was the charging regulator. They are covering it under warranty, but said they are behind at the factory 2-3 weeks to get the part sent out...
Overall it has been a little frustrating since I have almost 5k into it... But, the service has been good and it seems as though they are standing behind their product..... We shall see if this fixes the issue.
