>>1289866>Antenna.Still a shitty receiver/front-end.
Mine doesn't transmit anywhere close to its rated power output.
Figure out the channels, and band plan within FRS/GMRS. Not all the channels are the same power. (14-22 are going to be the highest-power ones.)
Regardless of whether you're on a baofeng, sporting-goods-store radio, or commercial/professional stuff, portables are going to be line-of-sight unless you're through infrastructure.
Baofengs are shitty radios.
