I use one of these
https://www.sdr-kits.net/index.php?route=web/pages&page_id=68_68
For frequencies below 30 MHz a sark100 would do. Google sark100 for a
local supplier. You should also check out the miniVnwa.
Of course you could make one yourself with an MSP430, a dds oscillator and
a return loss bridge. There are plenty of Arduino designs you could clone.
Back in the day when I was using MSP430s for ham radio work I think Yannick
posted a design.
But as the previous poster suggested you really should post this question
to one of the many VNWA groups.
Good luck,
Steve
