The RigExpert Stick 230 is a versatile analyzer designed for measuring SWR, return loss, and other parameters of cable and antenna systems within the frequency range of 100 kHz to 230 MHz. It facilitates tasks such as quickly checking antennas in various conditions, tuning antennas to resonance, comparing antenna characteristics pre and post-events like rain or hurricanes, and measuring capacitance or inductance of reactive loads.

With a frequency range from 0.1 to 230 MHz and 1 kHz resolution for frequency entry, the RigExpert Stick 230 offers measurements for various impedance systems including 25, 50, 75, 100, 150, 200, 300, 450, and 600 Ohms. It provides a wide SWR measurement range, R and X range, and multiple display modes for parameters like SWR, return loss, R, X, Z, L, C, Magnitude, and Phase Angle at a single frequency, as well as SWR charts and multé mode for multiband antenna checking.

The RigExpert Stick 230 features an RF output with a UHF connector, a square signal shape from 0.1 to 230 MHz, and -10 dBm output power at a 50-ohm load. It is powered by a 3.7V Li-Ion battery and can also draw power from a PC or DC adapter via USB. The analyzer includes a 200×200 monochrome e-paper display, a waterproof keypad with 2×3 keys, English menus, a USB connection to a computer, Bluetooth v.4.2 BLE, and comes with a 2-year warranty.
