boost range on garage door opener receiver

[richard295]

garage door remote operates on 310mhz. Stanley secure code     Antenna from garage door opener control is a small 9" wire hanging down.  probably 22 gauge or less
How can I boost the range of this opener.  Do I add some kind of antenna or extend the wire?  Anything I can use?

Richard,

Without a lot more detail it not possible to give an answer, but its probably not worth the effort unless you are after a learning experience or you really love playing with stuff.

Make a 310mhz yagi, connect it to the control box instead of the wire and point it towards the door.
This will reduce range in all the directions you don't need and boost range it in the direction that you want.

That's what I did, added long wire. Don't know what the frequency of mine.

The wire is designed to be a rough quarter wave antenna. Better results are obtainable using a short coax cable to extend it ( solder core to the antenna point and shield to the board ground plane next to there) to a better antenna. A dipole at the end using the same length as the original connected to shield and centre will improve things, or you can get an antenna for those receivers that improves things.

Just note though that too much signal is no good, as the receiver is a superhet design, and too much signal will stop it working. Best is to just move the receiver out of the motor unit and mount it near the door on a non metallic wall. It likely is a single black box with 3 wires connecting it.
