Yaesu: dummy load recommendations

[Delivers1234]

hi. i have a ftm-100d yaesu and I'm setting up pdn and wires-x. I want to be safe and have a dummy load. it outputs 50 watts.
any recommendations?

This is one of the better deals out there, rated 250 watts through at least 1GHz and it has a sample port to feed frequency counters and other test equipment. You can also stick a rubber duck antenna on the sample port for short range on air testing while into the load. These were many hundreds of $$ new and surplus about $45 including shipping. This load will serve you well into the future with 100w HF radios, medium size amplifiers, etc.

Any idea what the attenuation is at the sample port. I tried finding a spec sheet, but my Google-foo is weak today.

I mapped it out and it varies with frequency as most do. I’m away from home at the moment but remember it’s around 30dB @ 800, 35dB @ 450, 40 @ 150 and higher on HF. I use one a lot when testing repeaters well in excess of 100w to save the load in my HP service monitor. The sample port is useful for basic desense testing on repeaters with duplexers where you terminate the duplexer with this load then generate into the sample port to get a weak receive signal, then turn on the transmitter and check for any degradation.

Oh, and since this info is for the OP, let’s not find out a moderator bought the last one!
