measure vswr

Hiall.
It is possibile to read the vswr somewhre in a radio ?
Or there are cheap systems to do this in 5GHz ?
thanks

it’s not possible to measure this with a wireless card, but you can use other equipment like mentioned here:

Thank you, but 20K euro is not properly as I call cheap !! :wink:
I know that a vector analyzer is the answer, but I ask if there is a dedicated hardware (1K euro) to do this.

maybe this? http://www.gnswireless.com/PM-2458.htm

no idea if it works

thanks.
does someone used this stuff ?
or does someone knows someting of similar (also surplus)?

thanks
