I would like to continue the questions regarding external antennas. So far, all I can find is the general consensus that an external antenna will enhance the performance of a GPSr. I would like to find out if anyone can tell me specifically which external antenna will provide the best performace for (in this example) a Garmin 60CS. Whether the antenna be a Garmin 27 or 25 or one of the Gillsons, which one is the best? One additional question, anyone have any idea what impact longer cable length would have on an external antenna???
Thanks...
