BNC 50 Ohm Terminator, 5-Pack BNC Male Plug Cap Protective Cover for VNA, Signal Analyzers, Coaxial Cable Adapter Connector

I bought the 10 pack of 50 ohm BNC terminators. Build quality is solid. They all worked as expected, though one of them had a slight burr which caused it to hang up when being disconnected until it had been worked a few times. In terms of accuracy, all 10 measured in at 1.00:1 from 3.75MHz through 28MHz (the range I chose on my VNA) so they are, at least good enough for terminating measurements in the HF range. The impedances I measured over that range for all of them were between 49.9 and 50.4 ohms, with almost all of them in the 49.9 to 50.2 range. A test on one of them that showed 50.0 ohms across HF showed a range of 50.0 to 48.3 ohms from 1 to 450 MHz, so decent up into low UHF. I would not expect the others to differ materially from that, but I did not test all of them.

Good quality and conveniently marked 50 ohms on the end cap. I don't think I will be buying anymore expensive RF terminators when these do the job just fine.

At some point in your amateur radio or RF test gear addiction, you realize that you never have enough terminators on hand. And this is tempered with the realization that you can tell the difference between different ones you own when doing some sorts of tests. I wouldn’t chose to use these for device calibration, but I can read deeper into return loss for some tests with these than other 50 ohm terminators that I have.

Fit great, made well, measured at 51 ohm.

43ohm, 48 ohm, 51ohm, 53ohm, 57ohm at DC. SWR sweeps are within acceptable ranges except that 43 ohm one... it was iffy, didn't plan on it being used as an antenna so that's not a huge deal. The great thing about the oddball ones is that if their signatures unique enough they will help you differentiate the wires when you're trying to trace where a random wire is leading. I paint the heads with color nail polish and a numbers given per each color of the rainbow. this batch was ok, I have really wild ones from another seller than had 5 ohm and 100 ohm impedances. My batch wasn't that bad but condolences for the guy who may have used a 5 ohm impedance to terminate a 50 ohm line though. in the RF world a short is a feed point.

I purchased a pack of 10. Tested immediately with Dual Banana BNC Adapter and Fluke 8060A. Results are excellent. 49.81 49.88 49.89 49.94 49.97 50.02 50.04 50.06 50.08 50.17 I like very much they have engraved value 50 Ohm. Good for my need, to estimate self noise of various signal analyzers, preamplifiers. Great value for money. I obtained 10 of them so I always have a way to confirm noise reading not influenced by imperfect termination. And I don't think some people will succeed expecting power above 1/4W from a built in resistor. No cooling inside, no space for power resistor. I think a fraction of 1W would be best power rating estimate. Positively this type device is not designed for applications with 0.5W power applied to 50 Ohm. Overall I am happy with this purchase.

All 5 are 50 ohm +/- .2 Exhibit minimal reactance. Used for calibrating a NANOVNA and line testing.

Overall very satisfied. Good terminators for tuning our cavity band pass filters. Most of them measured very close to 50 ohms.

All five BNC terminations tested good and within specifications.

Good quality for the $$$

予想よりも小型で使いやすい

Excellent for terminating unused inputs on test equipment.
