# Comet CAT-300 1.8–50 MHz Manual Antenna Tuner

The **Comet CAT-300** is a high-performance **manual antenna tuning unit (ATU)** designed for precise impedance matching across the **HF and 6m amateur bands**. Engineered to support a wide range of antenna types—including dipoles, verticals, long-wire antennas, and mobile whips—the CAT-300 enables efficient transmitter operation by minimizing reflected power through manual LC network tuning.

Utilizing a robust **T-network matching circuit**, the CAT-300 allows operators to manually adjust inductive and capacitive parameters for optimal SWR across **1.8 MHz to 50 MHz**, making it suitable for multi-band HF base stations and mobile installations.

With support for transmit power up to **300W (SSB/CW)**, the CAT-300 is ideal for:

-   Multi-Band HF Base Stations
    
-   Manual Antenna Matching
    
-   Non-Resonant Antenna Systems
    
-   HF Vertical / Long-Wire Antennas
    
-   Mobile HF Operation
    

A built-in cross-needle SWR and power meter provides real-time forward/reflected power monitoring during tuning.
