HH-N2RS Mini Mobile Antenna (Yellow): Ultra-Compact 9 cm Dual-Band VHF/UHF (144/430 MHz) PL-259
Engineered for mobile radio operators, urban commuters, utility vehicle crews, and amateur radio operators operating in clearance-restricted environments. The high-visibility yellow HH-N2RS is built specifically for vehicles frequenting underground parking decks, low garages, car washes, and forested off-road tracks where standard full-length whips are prone to snagging or mechanical damage.
Key Features & Operational Benefits
- Ultra-low 9 cm form factor: Completely eliminates clearance issues with overhead barriers, automated garage doors, and tree branches without requiring antenna removal before parking.
- Dual-band 144/430 MHz resonance: Operates across both 2 m and 70 cm amateur allocations from a single mount point, enabling reliable simplex contact and local repeater access across town.
- Direct UHF-Male (PL-259) base termination: Threads directly onto standard SO-239 heavy-duty magnetic mounts, trunk lip brackets, and fixed roof mounts without cumbersome RF adapters or lossy connectors.
- High-visibility yellow radome: Increases antenna visibility on utility roofs and service vehicles while providing sealed environmental protection for internal matching components against road salt, moisture ingress, and UV degradation.
- 50 W continuous power handling: Readily accommodates the output stages of standard dual-band mobile transceivers without inductive coil overheating or impedance drift during transmission.
