Having this device in college when I was doing E&M would have been an absolute game changer. The closest thing that existed was an MFJ antenna tuner for Ham Radio that only measured S11 at one frequency, and cost around $500. The next step up was to buy used equipment, which was four figures or more. Having something that goes to 1 GHz, does both S11 and S21, and only costs $50? Unreal.

Having used a modern VNA, the NanoVNA would feel cramped now... but still: E&M would have been so much easier to understand with one of these, and a few labs.

It’s utterly depressing watching people fish out cash for an MFJ tuner these days. They still sell the things and they still command a stupid price for a thoroughly inferior device.

The two guys I know who still own them only do so because they are Sinophobes and MFJ stuff is (terribly) assembled in the US still.

Indeed.

MFJ in the amateur radio community is called "Mighty Fine Junk" fairly often. I have purchased some things from MFJ, but I notice that I now avoid doing so unless I'm desperate.

no one confuses gear from MFJ with "high quality". cheap stuff, that whets your appetite for the good stuff.

and yes, i have an MFJ tuner and the 20 meter QRP rig they sell. it is a ford or a chevy, not a lexus or a mercedes. (both items were received with parts loose and had to have some re-assembly).

Ha ha, I had to use a slotted line.
