🔄 Swap Adapters in Seconds

The antenna base features an FME connector, with 6 interchangeable 50-ohm RF adapters included: PL259, N-Type, TNC, BNC, SMA-Female, and SMA-Male. This modular system allows seamless compatibility with most radio equipment.

⚙️ True 50Ω Impedance — No Guesswork

Both the antenna and included connectors maintain a strict 50Ω impedance, ensuring optimal signal transfer and minimal reflection.
✳️ Why it matters: Impedance mismatches cause SWR to spike, reduce transmission efficiency, and in worst cases, damage RF equipment. Unlike low-quality adapters with wild, undefined impedance, the GRA-FX1 delivers true RF-grade matching.

🌀 Built with Memory Steel

The whip is crafted from flexible memory steel – bend it, twist it, stuff it in your backpack – and it bounces right back into shape. Built to survive rugged outdoor use without deforming.

☔ Waterproof and Field-Ready

 
All components are waterproof. Whether in your go-bag, mounted on a vehicle, or deployed in harsh environments, the GRA-FX1 is designed to perform.
