Bullet Points (Key Features)

PRECISE DUAL-BAND COVERAGE: Expertly tuned for optimal performance on the core amateur radio UV bands (VHF 144-148 MHz & UHF 430-440 MHz). Ideal for satellite communication (SATCOM), ham radio QSOs, and critical outdoor emergency communication scenarios.

HIGH GAIN & LOW VSWR: Features an integrated cross-shaped structure with 4 VHF and 7 UHF elements, delivering exceptional signal gain (7dBi VHF, 11dBi UHF) and a low Voltage Standing Wave Ratio (VSWR ≤1.5) for strong, stable, and clear signal transmission.

TOOL-FREE QUICK ASSEMBLY: Get operational in under 3 minutes! The full quick-release design with hand-tightened screws requires no tools. The main beam has clear frequency markings for fast and precise positioning, perfect for rapid deployment in the field.

LIGHTWEIGHT & DURABLE: The main beam employs a hollow design, achieving a perfect balance between structural strength and minimal weight. The entire antenna weighs just 440g (0.97 lbs), offering outstanding portability and durability for mobile use.

PLUG-AND-PLAY COMPATIBILITY: Equipped with a standard SO-239 (Female M SL16-KY) connector, it directly interfaces with most ham radios, walkie-talkies, mobile transceivers, and satellite receivers without the need for additional adapters.

Product Description

Unleash Your Communication Potential with a Professional-Grade Dual Band UV Antenna

Are you a ham radio enthusiast, a satellite communication explorer, or in need of reliable gear for emergency preparedness? The 5-Star Dual Band Antenna is engineered to meet your demands. It combines high performance, portability, and user-friendly operation, redefining what you can expect from mobile communication.

Engineered for Superior Performance

Optimized Cross Structure: This antenna integrates 4 VHF and 7 UHF elements into a precise, lightweight octagonal framework. This innovative design ensures maximum signal capture across both key amateur radio bands.

Advanced Gamma Matching: Utilizes gamma matching technology to optimize impedance efficiency and significantly reduce signal reflection. This results in a low VSWR and more of your radio's power being radiated effectively as a clear, strong signal.

Robust Power Handling: Safely handles up to 50W of power in FM mode, making it suitable for a wide range of mobile and fixed station applications.

Designed for Portability & Ease of Use

We understand the needs of outdoor and on-the-go operation. Weighing just 440 grams, it is incredibly lightweight and packs down small.

Rapid Setup: The tool-free, quick-disassembly design allows you to assemble or dismantle the antenna in seconds using only hand-tightened screws.

Calibrated Installation: The main beam features clear "V-Section (145MHz)" and "U-Section (435MHz)" markings, guiding you to a precise setup every time for optimal SWR and performance.

Versatile Application for Every Scenario
This antenna is the perfect solution for a variety of uses:

Amateur Satellite Communication: Precisely tuned for contacting FM satellites and receiving data from weather satellites.

Ham Radio Communication: Enhance your mobile or base station's signal reach and clarity for both voice and data modes.

Outdoor & Emergency Communication: Its quick-deploy capability and reliable performance make it a critical tool for ensuring communication lines are open during expeditions or disaster scenarios.
