Quick remote start question

[sageuvagony]

Hey guys I had installed a remote starter myself on my civic about 2 months ago. The starter unit itself has a long black wire which is the antenna. I have no idea where to put this. I routed it through the firewall though the engine into the front bumper but I dont think its getting best reception there. I dont like how I have to stand about 15 feet from my car to just start it with a remote. Does anyone have any better ideas as to where I should route this wire? The manual did not mention that at all. The wire isnt really long enough for it to be in the back bumper. Is there anyway to extend it or make the antenna better? Its just a black wire that comes straight out of the starter unit itself and has no plug. It just comes out. Any help is appreciated.

Thanks,
Richard
