I bought a Mini VNA for ~150. Works great. They show it as 100k thru 1300MHz but the RF out quits at around 600MHz. I've swept cavities, checked HF and VHF/UHF antennas. Love it. I could use it to align an AM broadcast directional array!! No need to lug a heavy OMB around. Does Smith charts! The multi SWR and wide scan comes in handy. Trying to identify an unknown antenna at the top of a tower with 500ft of Heliax?? This makes it a breeze if all is good. Built in TDR shows if feedline is ok as well
