For a mobile radio I have a Yaesu FTM-500 I dash mounted the control head using Tackform mounting system and for the radio body I used the Mountains2Metal under dash mount. I am currently using the COMPACtenna LMR-I Land Mobile Radio Antenna which is wide band and allows a good match between GMRS and 70cm and that is mounted to my driver’s side A-pillar. For portables I carry two BridgeCom Systems Echo GMRS handhelds.
Thanks @AB8DT
Did you use the Mountains2Metal antenna mount for your antenna?
