FRS license-free
Retevis RB48 (FRS 4-pack)
Rugged IP67 FRS pack for job sites, farms, and glove-box emergency pairs. No repeater access — short range only.
None (FRS) · Budget pack ($80–$120)
Quick start
First-hour checklist
- Charge all four units before storm season.
- Assign channels by role (e.g. house, barn, vehicles).
- Understand range limits in Appalachian terrain — FRS is line-of-sight.
- Pair with GMRS or ham layer for longer range; FRS alone is not enough for estate coverage.
When to go mobile
Handheld limits — mobile upgrade path
RB48 is intentionally short-range. GMRS mobile or ham mobile is the next step when FRS cannot reach the barn from the house.
