Our Verdicts
Garmin inReach Mini 2 Satellite Communicator
The inReach Mini 2 is the premium last-resort layer. It belongs in the kit when a balcony, roof, courtyard, or evacuation route gives you enough sky view to send messages after cell service fails.
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.
