Description
Specification: Item Type: QRM Eliminator Material: aluminum alloy Principle: The QRM Eliminator plugs into the antenna feedline without requiring any further modifications to the radio. The box has a built-in PTT control which allows the Eliminator to remain connected during transmission. However, an additional auxiliary receiving antenna is required, such as a 2m antenna or just a couple of meters cable in the cabin. The unwanted signal is received with both antennas resulting in different phases. The QRM Eliminator now allows you to adjust the phase angle and amplification in order to cancel the unwanted signal before it reaches the receiver front-end! It is based on a totally innovative concept and cannot be compared to normal "noise suppression" performance. Package List: 1 x QRM Eliminator 1 x 3P Power Control Line 1 user manual Note: There is a deviation of 0.5-1mm between the dial and the dial pointer.
