[TowerTalk] VNA

[Máximo EA1DDO_HK1H]

I guess;

For bench work only, used with PC, VNWA is best option actually.

For bench AND field use (no PC needed), KC901S+ is best and more completed. It is like a VNWA with battery and screen, up to 4 GHz.

Budget field models are Sark 110, AAxxx RigExpert models, etc.

without getting into what's good/bad because I've not looked at it in
any detail, there's a whole crop of newer small VNAs these days

There's also mention of a miniVNA, but it doesn't seem to be available
any more.


The TAPR/TenTec and N2PK appear to be no longer readily available as
