Here are some GMRS products that may be of interest.
I have these myself and may update my experiences with them as time passes.
GMRS radio
KG-100G plus
Antenna - GMRS
Midland MXTA26 (paid link) - 2023-11-27 I just received this so I cannot say how well it works.
Ground Plane Mount kit (paid link) - 2023-11-27 I just received this for the midland antenna, so I cannot say how well it works.
Coax
KMR-400 Coax (paid link) - Coax with specifications, that are ok for vhf/uhf. Longer runs over 100' may need coax with better specifications. This is generally good enough.
