V.S.W.R. meter Introduction VSWR. Forward and reflected power direct digital readout, without any calibration. Maximum measurable power range up to 120W. low insertion loss (0.3 decibels or less) structure allows it to be permanently connected. Build in Frequency counter . All Funtion display ( Frequency Counter ,Powe SW-28VU 125-525MHz SW-28HF 1.5-60MHz SWR & Power Meter This S.W.R. & Power meter is a highly accurate RF meter for measuring Forward Power, Reflected Power, and V.S.W.R. Main Features: · O-LED meter display for easy reading. · Forward RF power readings, switchable to indicate either average power. · Reflected RF power readings. · V.S.W.R. ratios. · Convenient control for easy operation. Manual Wholesale Quotation Shopping SURECOM SW-28 SWR & Power Meter Instruction Features: - According to the fitting algorithm of the characteristics of the detector diode, coupled with the dual-reference segment detection, the accuracy in the power range of 0-120 watts is better than 5%. - 5 kinds of interface display methods, choose according to your preferences , one-click switching. - High-speed average detection method, real-time efficiency display. - Buzzer alarm when a standing wave is greater than 2.0. - Built-in lithium battery, which can be used for more than 100 hours on a single charge. - Multi-function buttons make it more fun to use, reserve space for adding functions in the future and provide an additional interactive method.

SAVE & EXIT How to Use : The S.W.R.meter is connected between the r adio (TX) and the antenna, as close as possible to the transceiver (use a cable of max. 40 cm like Test Jumper. 1)Check all connections. 2)Press the key of the microphone PTT to pass into the transmission and keep it in this position. 3)Read data of S.W.R. / Forward watt / Reflected watt What is a high SWR reading? 1.5 -> 2.0. Your antenna is acceptably tuned and should work fine. 2.0 -> 3.0. Your SWR reading is slightly high, it shouldn't damage your radio, but you should try and tune your antenna to bring down your SWR reading. Above 3.0 or more. Your antenna isn't tuned acceptably and could damage your radio. If you have related videos, please share with us, please contact us
