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

works fine

Nice small load works great for my needs in my hobby in CB repair my radios

Great little dummy load perfect for medium to low power. Compact design great for testing and troubleshooting.

it works okay.

If you are a ham operator this is a must have item , MFJ very good equipment !

This dummy load was DOA (dead on arrival). I tested with an ohmmeter and then with a Nano VNA, it was open circuit. I took the case off and inspected it, and did some probing with the ohm meter, the actual big fat resistor was 51.5 ohms, which was within the specification, that was not the issue. The problem is that one end of the resistor clamp relies on a push fit contact with the aluminum case for the return earth path. Aluminum oxidizes to produce aluminum oxide (AL2 O3) with is an isolator, so there is an insulator between the 50 resistor and the case. Ive read other reviews where people have fixed it, well aluminum can oxidize in as little as 1 month so I would not trust that fix. Im not going to risk my $1000 transceiver on this piece of junk. This is a very poor design, has a fatal error and can only be fixed by installing a dedicated copper earth return wire back to the connector. So I guess its true what I read online MFJ = Mighty Fine Junk

What can I say, its a big resistor in a box! You would think that they could have the greenest newbs assembling these but maybe I give newbs too much credit. I opened the box and found one of the case screws started at about 30 degrees from straight on and only screwed about half way so the screw was sticking out a good 1/4. I removed the screw and installed it straight and fully without any issues but it seems ridiculous that something this simple was brushed over at the factory.

works great

Allows m to test my radios without going on air

I used it to check out the feedline to my antennas.
