Garage door rf remote amplifier ?

[ItsMike]

Hey everyone,

I've got this remote controlled gate in my neighborhood which is controlled by an rf remote transmitter.

The range of it is about 30 meters and since I'm super lazy I wonder if it could be extended to be able to open it without leaving my apartment which is 100 meters away (or so) + lots of walls in between.

Is that even possible ?

Not legally no.
The simplest solution would be to use a longer antenna, the antenna's on those types of remotes are kept short in part to help limit range.

do you know about where is remote's operating frequency?

 

[ItsMike]

No idea what is the operating frequency, but I would guess it's either 315MHz or 434MHz.

may be as Sceadwian said that you can try to expand antenna length. more than that you can add a small wideband RF PA for that frequency. but it's harder if it must built in your remote pack, i think.

The best way if you can find the freq of the transmitter is to increase the size of the
reciever antenna for some security frequencys in the UK you can buy mini yagi dipole
antenna with high gain
