I recently installed two electric gate openers on a gated drive. The
remotes work fine, but have a limited range (200 - 300 foot). How can
they be modified to transmit a bit more power to open gates at 500 foot
distance?
Increase the sensitivity of the receiving part of the system by
designing proper antenna at the working frequency.
Any ARRL book will be helpful.
The remotes work from button batteries so increasing their transmitted
signal is more work than it is worth.
On the other hand if you are on "sci.electronics.design", I have seen
gates operated by phone, so you ring from your mobile the number of the
gate, from whatever distance, the gate opens, detects passage of car and
closes. Or closes after some time delay when NO car passes.
The ball is in your court;^)
Have fun
