Open Box MFJ 1026 Noise Canceller SN100175
OPEN BOX - Like "NEW"
1.5-30MHz Deluxe Noise Canceller
The MFJ-1026 is designed to reduce noise or interference, or improve desired signals, before the noise
affects sensitive receiver circuits. Unlike conventional noise blankers, the MFJ-1026 can be effective on
all types of noise, including interference (QRM) from unwanted signals. The MFJ-1026 allows the user
to adjust both phase and amplitude while combining two antenna inputs. The antenna inputs can be
from two external antennas, or an external antenna and the MFJ-1026 internal whip antenna. The signal
output for the receiver is the vector addition or subtraction of signals from two separate antennas. This
allows unwanted noise to be removed or desired signals to be enhanced. The MFJ-1026 is optimized
over the range of 1.8 to 30 MHz.
The MFJ-1026 turns your antenna into a directional receiving phased array! 60 dB null wipes out interference and noise . . . Works on all modes including . . . SSB, AM, CW, and FM . . . Eliminate unwanted signals . . . Expose hidden stations!
Plug your station antenna into the MFJ-1026 and your antenna system turns into a directional receiving array!
You can place a null up to 60 dB deep on any type of noise and interference arriving from any single direction and wave angle. Wipe out interference and noise before it gets into your receiver!
It works on all modes -- SSB, AM, CW, FM -- and frequencies from 1.5 to 30 MHz. You can instantly change from nulling to peaking a signal at a push of a button and improve weak signal reception!
Wipe Out all types of Noise
Wipe out . . . lightning crashes from distant thunderstorms, severe power line noise from arcing transformers and insulators, lamp dimmers, touch controlled lamps, electric drills, motors, industry process, TV birdies . .
Eliminate unwanted signals
Strong local ham overloading your sensitive receiver? Can't copy your QSO? Cast a deep null on him and literally take him out -- you won't even know he's there.
Expose hidden stations
You can dig out a weak station hidden under a powerful one on the same frequency! Null out your local AM broadcast station. Underneath, you might find an exotic, distant station you've never heard of.
Works on all modes 1.5 to 30 MHz
Works on SSB, AM, CW, FM, RTTY, SSTV, Packet, and Pactor -- all modes. It works on all frequencies from 1.5 to 30 MHz, including all MF and HF amateur bands and shortwave broadcast.
More Effective then a Noise Blanker
Interference much stronger than the desired signal can be completely removed without affecting the desired signal.
Prevent overload by canceling noise before it gets into your sensitive receiver.
The MFJ-1026 is effective with all types of interference and on all modes. Signals can be peaked or nulled.
Better than Phased Antennas
The MFJ-1026 and your antenna can . . . electrically "rotate the array" while the antennas remain physically stationary . . . adjust both direction and wave angle of null or peak . . . change from nulling to peaking with the push of a button . . . ignore mutual coupling effects as phase and level are adjusted.
Use the MFJ-1026 as an adjustable phasing network. You can combine two antennas to give you various directional patterns and improve receiving signal levels.
Examples . . . two verticals become a steerable array . . . your Beverage and your transmitting antenna can enhance weak signals . . . two parallel staggered Beverage antennas can improve front-to-back ratio or steer nulls.
Connects between transmitting antenna and transceiver. To null, adjust amplitude and phase controls for minimum S-meter reading or lowest noise. To peak, push reverse button. Use built-in active antenna or an external one. Has near constant amplitude phase control.
RF sense T/R switch bypasses your transceiver with you transmit. Adjustable delay time. Uses 12 VDC or 100 VAC with MFJ-1312D. 7½W x 2½H x 6D inches.
