    Installed an Autopage remote start alarm system in my truck over the weekend. I wanted to hide the send and receive antenna for aesthetic purposes. Since my truck already had a 900mhz antenna mounted in the roof, I decided It would work perfect with my 900mhz alarm system.

    All it required was removing the old monopole antenna and soldering on a coax lead. Took me 20 minutes and the results are a huge improvement.


    I did cut off the extra coax to as close to the board as possible. It's only about a foot long to the mount. The ground stands are cut as far back as possible so they don't short out. For some reason this setup does not need a ground soldered. The stock antenna was just a straight metal whip.

    According to the FCC website this guy transmits at 22db. Using google earth, I determined that I can get about 1,500 feet of distance with this new setup. Not quite the impossible 1 mile that they advertise, but still good enough for me.

    Congrats on the DIY install. Fun, huh? Yes, those door lock wires were tough to get to. I have big hands, too.

    Another (easier) way to do the antenna is to remove the hand grip, pop off the pillar cover, and string the antenna wire up along the pillar. This is what I did when I installed my Clifford system a couple years ago. No cutting/splicing wires and I often get 1/4 mile range depending on conditions. Great for starting my truck from my office before heading home in the dead of winter.
