I kinda wonder if this was done as a goof, defiantly made me cringe thinking of people who are actually trying to learn from stuff like this. |O
really crazy part it looks like they were using it to trying to sell products... DOH :palm:

Abject fail on the soldering, to the point someone doesn't actually know how to solder sadly and anyway... why not crimp the centre feral onto the inner conduct with the same crimp tool. Finally and rather weirdly, what is actually being achieved?... the cable looked to be standard TV coax with rigid copper coated steel inner so F-type connector would be the norm with no added feral with the connector to the screw into a spliter/joiner or TV set....

I assume the center pin is intended to be crimped? It seems that many YouTube videos show them being soldered (with varying levels of skill :p)
peteb2: Cable TV isn’t the only use for coax. The video clearly says it’s RG-58 cable, which is perhaps the most common cable for 50 ohm lab use. (Cable TV uses 75 ohm cable, such as RG-59. And the F connector sucks.) SMA is a common RF connector. But even more generally... you make a particular cable assembly because, you know, you need it to connect other things. So you choose the connector types that will mate to the devices you’re connecting. Mounting an F connector does you no good if the device has an SMA jack...
