Antenna analyzer with precise, configurable measurement ranges - Flexible measurement range from 1 to 9.99 with user configurable step widths of 100 Hz, 1 kHz, 10 kHz and 100 kHz. This provides fine control across RF bands and helps with accurate tuning and testing. - 2.5 control buttons for quick, intuitive use. Easily select operating modes, tapes and advanced functions to streamline setup and operation. - Black housing design that is simple and durable, helping protect the unit from minor impacts and dust while keeping performance focused on RF testing. - Powered by an external 12V to 14V power supply with a 2.1 mm center-positive plug. Just connect the power supply and begin testing. Use scenarios - Field antenna tuning and verification: quickly check impedance and resonance on-site for towers, portable setups, or mobile rigs. - Bench or workshop RF testing: evaluate coils, coils networks, coax sections and other components with configurable frequency steps for precise measurements. - Installation checks for wireless links or ham radio stations: ensure proper tuning and alignment during setup or after changes to antennas or feeders.
