MFJ Enterprises Original MFJ-260C Dummy Load, 300 Watt, 0-650 MHz, Dry

Got it for my barefoot 7300. Itll be awhile before I can add an amp to my station, so this is fine for me for now. Radio saw 50 ohms, and I was able to play around and tweak my audio settings before putting my radio on the air. It did its job; I am happy with it.

Easy to use right out of the box. Used it along with my antenna analyzer to verify that my coax was working.

Works well, I pushed it to around 350 watts and it works great. No issues at all.

It works

Great product

Worked great for my purposes. Transmitted 100w into it with a great swr.

Nice and small

Dummy loads and antenna analyzer are the two tools youll go to everytime your radio gives you hiccups. The dummy load simulates a perfect antenna that can be used a reference point. I was originally going to give this a zero star review because it arrived to me open circuit. Inside a dummy load is a resistor. A non-inductive, pulse withstanding resistor, typically of this price level its a carbon composition or a carbon pile with horrific temper coefficients, but still. a 50 ohm 10% resistor. Mine was an open circuit, which I detected from my analyzer... thank god I didnt put it directly to my radio. The case was aluminum but the mating surfaces wouldnt conduct. I disassembled both resistor mounting brackets, after checking continuity and getting nothing. rubbed everything shiny with 0000 steel wool. reassembled, perfect. However the 259 bulkhead cant see it. I had to take the bulkhead off, polish the metal surface, reinstall/solder the bulkhead, and now R = 53. I essentially had to rebuild it from a full disassembly. Whoever put that hand written green QC sticker on it never tested. you know what they say, MJF = mighty fine junk Always test your equipment before using them to test something more expensive. cheers.

MFJ always produces great products And when I have any this company is the first place I run two to see great quality equipment

This is supposed to be a 50 ohm dummy load. It is an open circuit, very bad for the finals on a transmitter. The design uses the aluminum case as the ground connection for one end of the resistor. The case must be oxidized of coated. Do not buy this product. You can get the same functionality by not attaching anything to the output of your transmitter.
