Accuracy Test of OwlRC 5.8g SWR Meter - is it worth 100usd?

In this video, let’s see how the OwlRC 5.8ghz SWR meter stands up against a lab-grade VNA that costs more than 15,000usd, and find out if you should pay 100usd for it. Also, refer to the empirical data comparison below.

Empirical Data Comparison
---------------------------------------------
TrueRC RHCP crosshair (white dome):
5.8ghz OwlRC meter: Lowest SWR of 1.03 at 5657mhz (equivalent to reflection of -36.6dB)

20ghz KeySight VNA: Lowest reflection of -17.5 dB at 5945mhz
reflection of -13 dB for 5657mhz

IRC 8db RHCP Patch (white square):
5.8ghz OwlRC meter: Lowest SWR of 1.41 at 5775mhz (equivalent to reflection of -15.4 dB)

20ghz KeySight VNA: Lowest reflection of -17.8 dB at 5830mhz
reflection of - 15 dB for 5775mhz

Realacc Triple Feed Patch:
5.8ghz OwlRC meter: Lowest SWR of 1.27 at 5765mhz (equivalent to reflection of -18.5dB)

20ghz KeySight VNA: Lowest reflection of -26dB at 5645mhz
reflection of -23dB for 5765mhz

nice review terence, did you you consider that using the sma adapter have big influence on the data reading..i have test the pagoda antena with and wothout adapter, when i use the swr without the adapter the result is bad swr graph, and then i try to use tha pagoda with adapter the result is flat swr .

When you look on marker - you shall put market to TRACK mode or move it to desired place. On 7:10 for example, marker is totally off from minimal place.

This meter completely inaccurate.
No reference value at all.
Thank you for your review about this meter.

This is garbage - it shows all antennas VSWR=1 on wide range - complete junk.

This thing looks more like 20usd tops then 100.
