See more For about $30, including sales tax, I got what I wanted and needed. I wanted a 50W load with a quality UHF male connector (captivated center pin) on it that I could use with a low VSWR and a fairly flat performance profile thru the 440MHz ham band.

I expected the performance of the UHF connector to degrade somewhat above 300MHz, as that is the frequency where one should really switch to using an N style connector, but the VSWR as measured on my NanoVNA was no worse than 1.03:1 anywhere from 1.8 thru 450 MHz. Of course the resistive part of the overall impedance load would vary between 48 and 54 Ohms with the complex part of the presented load varying slightly capacitive (at most couple of hundred pF) to slightly inductive (max of 1.5 nH), but this never prevented the overall return loss at ANY frequency across that range was never any worse than 25-30dB. I couldn''t ask for more.

It was really cool to see the LCD readout on my NanoVNA simply trace a tiny spiral of circles around the 50 Ohm point in the dead center of the Smith Chart display across this swept frequency range. This is a real home run, IMHO.

One cannot expect a DC Ohmmeter to measure 50 Ohms nor a single RF frequency to read that same number with "absolutely no reactance contribution at all" at a single, selected RF point frequency. Only an RF sweep across the operating range of interest with VSWR, return loss, et cetera readings will tell one whether this will be a good quality load for one''s radio or other RF emanating device. This load meets that criteria for how I will be using it.

If you plan to operate at frequencies above the 440 Ham Band, say at 902 or 1296 MHz, or above...buy a load that has an N-connector input. That way you won''t get the impedance bump from a UHF connector''s physical design at those higher frequencies. An N connector input dummy load should give you a 1.5:1 VSWR (15dB return loss...a decent 50 Ohm match) up to 3 GHz. You should also use nothing but N connector males and females on all of your other RF connections...with NO inter-series adapters. As such, since I only use UHF connectors, I wouldn''t try to use this load above 500 MHz.

For my planned use, though, it''s a real winner at a very good price-point.
