I've been having this for over a year. Placed transmitter at the end of my carport (about 50' away) and would work fine. Purchased second transmitter and placed it at the end of my driveway (about 150' away) that one would never set off receiver... too far away I guess, UNTIL. I had about 50ft of 18awg stranded and insulated wire and wrapped it neatly and tightly around an big old rusty chisel. Hammered chisel into post that has transmitter screwed to. Connected the "chisel antenna" to the antenna of the transmitter and who'd of thunk it... IT WORKS FINE NOW. I haven't had a false alarm. Most recent event, A car pulled in and set off alarm and then leaves. The alarm is connected to a dvr which has a camera pointed at the entrance of the driveway. Alarm goes off, I look at monitor and see nothing after playback I see the car. I'm very excited that it works now, too bad it needs a little help to function reliably. I still think I'm going to check out dakota alerts wma-3000 next. It has 4 relays instead of the one the chamberlain supplies. Hope this is helpful and gets out to those who purchased this and were very dissapointed with its range as I was.
