FRS vs GMRSFRS = Low Power, Not Legal to Replace Antenna

GMRS = Requires an FCC License (fee and registration only)

GMRS Can Use Repeaters on GMRS Only Frequencies

GMRS Can Replace Antennas

GMRS Can Use More Power

Page 12: Mobile Radio Communications

FRS/GMRS Radio Weaknesses

Very Low Power

Very Poor Antennas

Results in Exceptionally Short Range

Not Well Suited For Use Inside a Vehicle (Signal Loss)

14 Channels Only (FRS) / 23 Channels (GMRS)
