Vine Antennas RST-928 – Advanced Band-Sync Detection • LPF Built-In • Full Digital Readout
Take your HF station to the next level with the RST-928, a high-efficiency 150W HF linear power amplifier designed for operators who demand clean, stable, and intelligent amplification. With automatic band detection, a 6-band optimised low-pass filter, and advanced protection circuitry, the RST-928 delivers powerful performance with total confidence. ⚡📡
Deliver up to 150W output power across 1.8–30MHz, with a clean low-distortion signal thanks to optimised LPF filtering.
The RST-928 automatically detects RF band information via your PTT sync cable, instantly selecting the correct low-pass filter.
Enjoy a clear, modern digital screen showing power output, SWR, and operational status — all at a glance.
Fine-tune your station with four selectable amplification levels, ideal for both QRP operators and higher-power rigs.
Operate safely with built-in protections including:
🔥 High-Temperature Protection
⚡ High Voltage & Low Voltage Protection
📡 High SWR Protection
Perfect for long operating sessions and portable setups.
Smart temperature-controlled cooling ensures stable performance during extended transmission periods.
Improved output filtering for clean, stable, and compliant HF operation.
