boost your car remote!!! video!
have you ever lost your car??? hit the open button on your car remote but your just too far =/ well i can teach you how to increase your car remote by 50 FEET =0
well it takes 5 min.s! have fun!
helping you save that coin!!!

Well, considering I went to school for electrical engineering, then went to the military for communications and worked with all different kinds of radio's I can tell you two things:
1. The guy got lucky
2. You have just as much chance of reducing range by doing this
Fortunately for you our transmitters don't have this exposed antenna, so you can't do this and mess up your remote. Radio waves are just that, waves, and they have a specific measurement just like a wave in the water. Antenne are tuned to match that wavelength. If you are trying to pick up a cell phone signal, a 4 foot long antenna is going to be crap. Why? The wavelength is measured at roughly 4in long. Now go open up a cell phone and you will find a 1in long antenna, this is called a 1/4 wave antenna. If you look and see those external cell phone antenna's for cars...4in long, full wave length antenna. Look at the cell phones that have antenna's that pull out, 2in long, or half wave length antenna.
As long as you stick to 1/4, 1/2, and 1/1 ratio's on your antenna you have relatively good performance (1/1 being best, but not always feasable when you talk about 40 ft long wavelengths). So really, before you do something like this you should research and find what wavelength the transmitter operates at, then calculate wavelength, then make your attena match.
I won't even get into the effects of bending the antenna like he did and what it does to radio wave propigation....

or get a good 2 way alarm. mine is advertised at 1+ mile range. never tried it from that far, but it works from pretty far. the only spots i never got a signal were from inside theaters. all my other alarms have had no signal. with this new one i have picked up signal with full bar in the same theater room. specially nice now with the weather. i can start my car up when the credits start rolling and its warmed up and nice and toasty by the time i get to it.

As an RF guy myself, some of the the best advice that I have heard in a few days.
