![]() ![]() Calibrate the readings SWR by REW trimpot on the reference meter connected in series to the antenna or using the load with known resistance, such as 100 ohms. Calibrate the Power Meter reading with trimpot FWR on reference instrument. Minimum voltage from directional coupler (SWR bridge) +2.55V For proper operation the device requires calibration. The forward voltage must be applied to the input port F, reflected to input port R. For this purpose it should be connected to the directional coupler of any design, say Tandem-match. ![]() ![]() LCD SWR power meter indicator for LDMOS MOSFET tube amplifier 2400W max The device is designed to display on the LCD alphanumeric display the values of the forward power and VSWR. Directivity of 22 dB from 26 dB 70 to 146 MHz. Cable - RG141 Band 70-146 MHz Power 1000-2000W Size 120 x 50 mm The configuration used in the Directional coupler works well over the frequency range of 70 to 146 MHz, with a coupling factor of 43 dB to 38 dB. ![]()
