The Stampfel VT5-S is a high-performance active HF multicoupler designed for serious shortwave and HF monitoring applications. Operating across 9 to 52 MHz, it enables a single antenna to feed up to five receivers simultaneously without any signal loss. Its advanced low-noise amplifier and robust design make it ideal for professional and amateur radio installations where reliability and signal integrity are essential.

Functional Overview

The VT5-S uses a precision low-noise HF amplifier followed by a push-pull output driver to achieve near-zero output impedance. From this virtual star point, a passive distribution network feeds five isolated outputs. This design ensures consistent signal strength and excellent channel separation, allowing multiple receivers to operate from one antenna without mutual interference.

Ideal for monitoring stations, DX enthusiasts, and laboratory test setups, the Stampfel VT5-S delivers professional-grade multicoupling performance in a compact and rugged package.
