Our Verdicts
Retevis RT97S Portable GMRS Repeater
The RT97S is the advanced GMRS product OutageKit was missing: a repeater for a licensed building radio lead trying to make floor-to-lobby or neighborhood RF coverage more reliable. It is not for casual renters, condo-board blanket use, or internet-linked networks, and it does not bypass GMRS licensing or station-identification rules. It belongs only when a responsible licensed operator can place the antenna, power the unit, and run a written channel plan.
ZOLEO Global Satellite Communicator
ZOLEO is the easier satellite messenger for households that will keep one phone charged at the command post. It is less standalone than Garmin, but the phone-first experience is easier for non-outdoors users.
