V85 Handheld Radio Antenna – VHF/UHF/868MHz 3.5dBi Rubber Whip Antenna for Walkie Talkie Two-Way Radio & Starlink Communication

Characteristic
Core RF Performance
Wideband Coverage: Simultaneously supports the VHF (66-88MHz), UHF (400-470MHz), and 868MHz ISM bands. Patented loading technology achieves a voltage standing wave ratio (VSWR) of ≤1.8:1 across all three bands.
Intelligent Gain Control: 3.5dBi dynamic gain design utilizes a 1/2 wavelength (UHF) and 5/8 wavelength (VHF) composite structure. Measured open-area communication range:
VHF Mode: 8-12km (5W transmit power)
UHF Mode: 5-8km (4W transmit power)
868MHz Mode: 3-5km (2W transmit power)
Impedance Matching: Standard 50Ω interface with built-in double-balanced transformers, effectively suppressing harmonic interference to -35dBc

Core Performance‌
Flexible, damage-resistant architecture:
Outer layer: Highly elastic TPU rubber, passed MIL-STD-810G 514.7 vibration test standards
Core material: Shape-memory nickel-titanium alloy wire, withstands >5,000 180° bending cycles
Environmental adaptability:
IP67 protection rating (1 meter immersion for 30 minutes)
Operating temperature range: -40°C to +105°C, passed 96-hour salt spray corrosion test
Ergonomic design:
Total length: 286mm ±2%, weighs only 58g
Anti-tangling thread construction, torque ≥ 0.6N·m

NOTICE

During the installation process, avoid any collisions.

It is strictly prohibited to disassemble the antenna components; otherwise, it may lead to poor antenna performance.

The installation position of the antenna should be free of any obstructions.

When used outdoors, it is necessary to equip with lightning protection facilities.

may contain electronic components. Do not discard them randomly.
