I am looking for a little advice and help My partner and I have and use a pair of GME 680 3kw handheld radios to talk whilst riding. My unit connects to Starcom1 unit which also connects to my GPS and iPod and has rider to pillion connection as well. My partner uses a simple PTT switch and headset with mic also from starcom. I would however like to increase the range and am looking to now attach an antenna onto my bike to try and increase the range. I am however unsure at the best way to do this. The GME does have a removable antenna so i do have the option to fit some type of coupling to the radio. Has anyone done something similar and which type of antenna would be most suitable? I have no idea about antennas and there are just too many out there to choose from?
