If you are determined to use a wireless device, you will have to
change the antenna.  Any form of dish or yagi will greatly improve
your chances.

I use three wired CarTels.  Those things are fantastic - they always
work and never false.  They don't have to be buried under the driveway
- putting one along side the driveway works well.  The controllers are
exposed from -40 deg. F to +100 deg F and never seem to need
adjustment.
