MFJ noise suppression signal attenuators are designed to reduce noise or interference, or enhance the desired signals, before the noise affects the sensitive circuits of the receiver. Unlike conventional noise suppressors, these units can be effective on all types of noise (QRN), as well as on interference (QRM) from unwanted signals. These noise cancellation signal amplifiers work on all signal modes and can transform difficult reception situations so you can finally hear, work and record this rare DX!
MFJ noise cancellation signal attenuators allow the user to adjust the phase and amplitude while combining the antenna inputs. One of the two antenna inputs can be connected to the transmitting antenna, and the other to an external receiving antenna or the internal whip antenna on the MFJ-1026. Or both inputs can be used with identical receiving antennas to create different directional patterns for optimal results. The output signal to the receiver or transceiver is the vector addition or subtraction of signals from two separate, balanced and in-phase antennas. This eliminates unwanted noise or improves the desired signals.
Some other phasing systems provide a limited phase adjustment range or change the signal level when the phase is adjusted. These MFJ units have an exceptional phase amplitude flatness facilitating adjustment.
The MFJ noise canceling signal amplifiers are optimized over a range of 1.8 to 30 MHz and contain the interface circuits necessary to operate with most modern HF amateur radio transceivers. Although these signal amplifiers contain internal RF detection for T / R (transmit-receive) switching, we strongly recommend the use of the external T / R control connector on the back panel for input. These units operate on 12 VDC or 110 Vac with an optional adapter, sold separately.
