Hi, all sorry to repost this but it got no attention on the other page, i'm new to the site but am already enjoying it. i have two questions to pose to you guys, and gal's i have a two channel door opener that i use for the gates at work first i would like to pakage this in a smaller case than the 4"x2"x1/2" original which is kind of bulky but my hinderance is the 9v batt that it uses is it possible to use some sort of smaller battery's or capacitor of some sort to help with size problem ? and second it is also rather weak and has a hard time opening a gate from inside a vehicle let alone standing outside nearly at the gate to get it to open. is there a way to boost the signal. i know that some car alarms work at 30-40ft and thefactory alarms work as far as 100ft i would love to have this kind of range is it possible? any help would be very greatly appriciated!! P.s. the opener appears to me made by the Linear company and it has dual 8 switch rockers and dual chips marked T800 4393. Thankx again!!!
