Re: Extend the range of a garage door opener
Just as with any Raido type transmission system, to increase the range you basically have 2 possibliities.... Increase the power on the transmitter and improve the antenna for better reception.
There's a 3rd possibility. A repeater, passive or active. Put in a passive repeater, half-way and no wires or power needed. It's often done for TV and FM reception. I've got two passive repeaters up on my hill for UHF and VHF TV.
