Anyone ever use one of these? Is it worth $55 or so? Looking at the manual, http://www.mfjenterprises.com/man/pdf/MFJ-1164.pdf, it is a simple LC fitler. 3 inductors, 2 caps and 2 MOVs. I am not a fan of MOVs as they offer minimal OVP protection and WHEN they fail they are very likely to catch on fire. The four outlets are spaced far enough apart to allow, the never to be dmaned enough, wall warts to be used. And the case is heavy enough not to slip around. If you are somewhat skilled, and willing to do the work yourself, you can build your own RFI filter that will be a lot more effective for a lot less money. http://www.hosfelt.com/ offers serval RFI filters, I like the Curtis F1600CA03. I don't need more then 3A per outlet, so I use a fitler for each outlet. Curtis and Corcom, and many other companies, offer heavier (Higer current) RFI filters. Unless you are using tube gear, or you are a ham with a "high" powered transceiver, or have even more radios then I do, I really doubt that you need a 25A fitler. The lower power Curtis or Corcom have a much higher effectiveness. The Curtis filters are only $0.35 each. A very good value. One of my favorite "tricks" is to use spare PC style IEC power cables and add a female AC mains connector to the other end that matches the device, and I have placed fitlers in line with EVERY RF noise producing device in our home. Very inexpensive and very effective. I doubt if I have more then $30 in all of my RFI mains filters and I have spare Curtis for new additons. Terry |
