How much range should I expect out of my system?

There are MANY factors to this equation from the length of your antenna (longer is better), length of coax (18 feet is optimal), brand of antenna- they are not all equal
(check out the Firestik FL series antennas)- antenna SWR tuned?, has proper antenna ground been achieved?, has the radio been performance tuned? how about all of the above for the biker you are communicating with and how much (white noise) are you experiencing today. (White noise) changes daily.

Below is approximations only.

1) Short antenna (6 inch rubber duck) non tuned radio. Approximately 50-100 yards.
2) Short antenna (1-2 foot) non tuned radio. Approximately 1/4 to 1/2 mile.
3) Long antenna (3-4 foot) and non tuned radio. Approximately 3/4 to 1 1/2 miles.
4) Performance tune the J&M radio – increase by 40-50%
5) Add our compressor to a GL1800 or a Harley – 5 miles typical.

About Performance Tuning

The Performance tune up increases the output of the radio by approximately 50%. The receiver gain is typically 20-30% over stock specs.
This modification includes the following changes in order to enhance the radio’s performance.
– Adjusting the modulation for maximum output without distortion.
– Aligning the receiver for optimum signal to noise ratio.
– Adjusting the squelch range
– Frequency adjustment to zero tolerance.
– Perform a complete check of all functions.
– Perform a visual of the circuit board for cold joints and flaws.

A properly tuned radio should be loud but also clear.
