PLZ-QRM Eliminator (1-30 MHz) HF Bands Aluminum Alloy

Principle: The QRM canceller is inserted into the feeder of the antenna without any other modifications to the radio. The box has a built-in PTT control to keep the canceller connected during transmission. However, an additional auxiliary receiving antenna is required, such as a 2m antenna or only a few meters of wires in a shed. The two antennas receive unwanted signals, resulting in different phases. The QRM canceller now allows adjustment of the phase angle and amplification to cancel unwanted signals before they reach the receiver front end!Features:The QRM canceller is inserted into the feeder of the antenna without any other modifications to the radio.Aluminum alloy outshell design, solid and firm, wear resistance and can provides long service time.Built-in PTT control to keep the canceller connected during transmission.Phase adjustable, two gains adjustable, easy to adjust by the rotation knob.The QRM canceller allows adjustment of the phase angle and amplification to cancel unwanted signals before they reach the receiver front end.Specifications:Name: QRM EliminatorMaterial: aluminum alloyColor: blacksize: 115 * 133 * 49mm / 4.53 * 5.24 * 1.93inweight: 355g / 12.52ouncePackage size: 150 * 150 * 50mm / 5.91 * 5.91 * 1.97inPackage weight: 361g / 12.73ouncePacking List:1 * QRM Eliminator1 * CableWe confidently assure you'll be satisfied with what you get.However, If there's a chance that you are not satisfied with our goods or something else, please let us know before leaving us a Negative feedback.
