scratchmann@Fpsychotic so it's good for 5.8GHz antennas?

erberes 25/01/2022
It's better than the NanoVNAv2 (3GHz) in every possible way, however it's good only about till 5GHz and that means that it does not unfortunately reach the 5.8GHz ISM band for S11 measurement (S21 works although it gets quite noisy there; for this in reality 4 1/2 stars if that was possible). The similar v1 (that goes till around 1.5GHz) required soldering SD card socket and crystal (for the clock if you cared) and the v2 was missing both, so this variant is better in that respect. It has a nice display and has SD card support (for me 32G newer one did not work, only 2G older one) but care is needed as it's possible to miss with the SD card the socket and it means that you have to disassemble the box to get it out. The noise floor is pretty good around 2.4GHz (tested with 60 and 65dB attenuation) and it has no trouble to show the S11 dip for such antenna. The biggest miss is that it's not suitable for testing 5.8GHz antennas. I've tested it with the firmware that I've received. As the firmware is in heavy development, newer ones can perhaps improve this a bit. For the battery you have to set the battery offset as it's likely to show incorrect charging status without it. It's goes also almost without saying that calibration for all setups is a must before any measurement (as for any VNA even professional ones).

Allora... Sono arrivati in 5gg da CZ la confezione era perfetta anche se non imballata praticamente in una busta e vabbè 0.o il visore è spettacolare da vedere, da indossare un po' meno 🤦🏻 sicuramente va riadattato io sono alto 2mt mi chiedo che uomo dev essere con una testa così grossa da riempirlo...nella confezione bhè c'è la batteria il cavetto della batteria un cavetto usbc una borsetta che bho 0.o e basta gente! 650 euro e nemmeno una spugnetta per pulire le lenti, una custodia zero. Le antenne sono 4 giocattoli consiglio di fargli vedere la finestra il prima possibile anche lì per 600 e passa euro 4 antenne decenti... Insomma belli ma non completi, spugna per il viso, porta antenne, antenne custodia e quant altro va aggiunto alla spesa. Grazie banggood

A beast of a flashlighg. Really good build quality. good thrower beam with moderate flood. At turbo mode, the light output it's astonishing for that price, but get's hot fast (as all other flashlights of this power, of course). Te UI it's very good, I like the ramp mode from 0 to turbo mode in 4 seconds and viceversa (so it's exponential curve, not lineal). Overall an exellent flashlight for the price, it's big, but it's very powerful.
