RFD-222RLF5, 222 MHz 10 Elements Rectangular Loop Feed (RLF) Yagi.

Introducing the RFD-222RLF10: Next-Generation Low-Noise VHF 1.25m Yagi

The RFD-222RLF10 is a cutting-edge, low-noise Yagi antenna designed for the 1.25 m VHF band. “RLF” stands for Rectangular Loop Feed.

Instead of a traditional folded dipole or simple dipole, we use a rectangular quad loop as the driven element. This design offers several advantages:

• Direct 50 Ω feed – no matching transformer required.

• Higher gain compared to conventional dipoles.

• Full-wave loop performance, resulting in exceptionally low noise.

By combining the loop feed with carefully optimized parasitic elements, the RFD-222RLF10 delivers high forward gain while maintaining a superior front-to-back ratio and low SWR.

After hours of electromagnetic code–based simulations and real-world refinements, we have achieved an antenna tailored for today’s RF environment, where electromagnetic interference is everywhere. The result is crystal-clear reception of even the weakest stations—and the power to be heard when you transmit.
