Im very happy with a recently acquired H4 from Gigaparts and the smaller and older Hugen version. Carl

I want to add to the list please? You want the nanoVNA so you can read the "antenna system" into your computer. Save the results. Then open up a program called SimSmith and analyze your system and

Thanks. ---? Ciao baby, catch you on the flip side?? 73 de W3AB/GEO ??? http://www.w3ab.org You can say "over", you can say "out", you just can't say "over and out".

You might find the MFJ easier to use if all you want to do is check SWR, but if you want more details, you want the NanoVNA.? I own two of them, will probably buy an H4 soon, and will also buy the V2

SMITH CHARTS !!!! Bill

I concur with what Dave sez, plus the freq range is seamless & you can connect it to a droid and/or windblows PC. I do suggest using a pair of SMA connector savers. I have some that are push-on,

I calculated a minimum loss resistor network, reducing the 2 x 14.8 dB from the HP fixture to 2 x 11.4 dB. Please see at https://www.rudiswiki.de/wiki9/nanoVNA#Crystal_measurement Attached are 2

Why don't you pay half a beer to the OP of this topic?

You will see them. It's just a matter of time.

Thank you Dave.? I have gotten great answers and enough courage to decide.? Just clicked the purchase the NanoVna H4.? I am really looking forward to having it on this next antenna project. Thanks

The MFJ's 1) do not cover the frequency range of the NANO's 2) do not offer the measurement accuracy of the NANO's 3) do not have the frequency accuracy of the NANO's 4) do not have the diversified

Didn't see any for the H4 version. ?___ Sent from my two way wrist watch 73 de W3AB/GEO?

Bummer. Thanks. ?___ Sent from my two way wrist watch 73 de W3AB/GEO?

Unfortunately not for the H4 version. @GEO BADGER, check post 1 of this topic.

Dan, here's my 0.02 worth RE nanoVNA versus antenna analyzers: One is an open source "vector network analyzer" that is continually open to updates and fixes and experimentation. It requires close

Thingverse has a few

I guess I missed this thread. Who/where can the case for the h4 be purchased or the 3d STL files downloaded.? ---? Ciao baby, catch you on the flip side?? 73 de W3AB/GEO ??? http://www.w3ab.org

It may assist in a high RF field environment. ?___ Sent from my two way wrist watch 73 de W3AB/GEO?

Hola José, The crystal parameters can be calculated as explained in the PHSNA User's Guide Appendix I, by Nick Kennedy WA5BDU. All formulas are there. It can be downloaded from here:

I am impressed.? I have never touched a 3D printer, or seen one in action.? Do you sell the cases? Please share what printer you use.? I might consider getting one.? I am always monkeying around
