Whether it’s a noisy switcher, power line, or engine, up to -60 dBm of suppression keeps the hash out of your rig and away from your ears.

Bring out that weak, low-band signal! This isn’t a dainty filter either.  The MFJ-1146 is rated for a total load of 40 A at 13.8 VDC, but even if you blow a fuse, a series of LED indicators tells you instantly which one
is out.

Worried about RFI getting in after the filters?

The MFJ-1146 has you covered! Properly grounded, the aluminum case will help keep RFI out. With four sets of Anderson PowerPolesTM and two sets of high-current binding posts, the MFJ-1146 is versatile enough for all of your power needs.
