WRITEUP: GM Remote MOD

You guys need to use a thinner wire, It's an antenna, It carrys no current or voltage.

Exactly. In my thread I used a 28ga. That is plenty to get you 100' of range if you run it up the A-pillar.

Even more if you relocated the box!

I didn't read the whole thread so excuse me if this is a repeat.

As everybody knows the remotes use radio frequency. That frequency is like a wave. For arguments sake lets say that wave is 10 feet from peak to peak. Now if you decide to make an antenna, ideally your antenna should be 10 feet long. At least in a perfect world. BUT you can divide up that wave and get pretty good performance. You can go 1/2, 1/4, 1/8, 1/16, etc wave. Of course the shorter the antenna the poorer the performance. Using an odd length will degrade the signal catching capicity. So if you decide to do this antenna mod just make sure you use the correct length.

On that note, do we know the frequency of the fobs?

I spy another rc pilot. Lol. I haven't been able to fly for almost 2 years now. Hopefully can pick it up again when I get back to the states.

Just for other people's knowledge, I don't know the frequency the system uses. But he is absolutely correct on the proper way to make it shorter.

It's 315mhz, so about .95m of antenna...

... antenna that's not shielded or effected by the cage effect under your dash or shielding by it running past wires with power passing through them and imposing Eddy currents.

Run a thin gauge wire up your A-pillar and into the roof per my write-up. You'll be satisfied. Believe me.

I wish you the best of luck getting back into RC. THANK YOU for your service to our great nation!!
