Yesterday a member here forwarded me some info on using different antenna's to improve the range on the Garmin systems. I read what he sent, then did some additional research. I ordered an "upgraded" rubber antenna for the handheld, it should be in sometime next week.Then yesterday evening, it dawned on me that I know a man that owns a large communications company with an office 10 minutes from mine. I called him up last night and told him that I want to increase the range on my Garmin, and told him what frequencies I am dealing with. Thursday AM I have an appointment to meet with one of his technicians. Here is what we are going to try. Using a ~48" magnetic mount antenna, with a 2.5 db gain, tuning it to 151-154 mhz. In theory the Garmin puts out 2 watts of signal. They said in reality, it probably puts out something more like 1.5 watts. Matching that with a tuned 2.5 db antenna, it should put out closer to 4 watts. This should, at least in theory, significantly increase the range.
Some claims I have read are. "upgraded rubber antenna" 4-5 mile range
Tuned magnetic mount antenna, 14-15 mile range.
Now, if I can achieve half of the claimed distances, I will be pleased.
Anyone else tried something like this, and if so, what results have you seen?
