I got a NanoVNA for about $60 and it works way better then I had any right to expect. If you have any need to figure out some kind of RF issue it is well worth the money for the amount of time you will save.

I used it to diagnose a VHF issue on a boat. The AIS was reporting high VSWR but only sometimes... It turned out that the antenna was seriously affected by it's angle relative to the metal poles that support the Bimini top.

Also, a lossy cable is not always a bad thing. A lossy cable can stabilize a PA if you are forced to have bad match at the load end.
