Thank you.? The posts in the mods area are informative, tho I do not understand the need for the pcb board? OR any bonding of the ground from the two connectors.? I could probably make such a case of something that would absorb impact.? ? I will keep researching.?
Again, Thanks

? Dan - look in the mods section (in Files) of the forum and look at the ideas in there for strain reliefs for the connectors.
browse the photos section as well.

I am brand new to nanoVNA h4.? ?Matter of fact, it is in the stage of "in the mail"But one thing I had observed in the ads online, was the likelihood of strain on the connectors, and therefore strain on circuit board.While I do not have a 3D printer, nor the knowledge of how to turn an idea into the physical item I desire, I can envision a protective case thatwould have a base tray longer than the VNA and all of its external fittings for SMA connectors.Therefore if it is dropped (yes, unlike many of you, I drop things occasionally) it would not become another paperweight.
I would also want the front sides to be elevated above the screen in such a manner as a cell phone case that help reduce cracking of displays.My Samsung Galaxy Note 9 has broken glass on the front and on the back (why they put glass on the back is unknown to me)I would like to see someone who has that capacity to make such available at a reasonable price.
Thanks for reading my babbling on something that has probably been discussed many time before I joined this group.

How are you doing?

I have purchased the H4 case from the OP to encorage and thank him for his
work, however its not hard to do.

I have designed the "yellow" attachment to hold the nanoVNA-H4 with its
case. If i detach it (to use the SMA connectors) , it still inside the
case, thus the 2 parts.

The connectors are 2 x so239 to SMA female adapters followed by 2 x sma
male to male adapters.

Don't forget to calibrate your VNA with all these adapters already fit, for
correct readings...

Hello! I made a case for my nanoVNA, but after seeing your case with the
end that supports the fixed connectors, I decided that would be what I
would like for my VNA. My enclosure is less than 4 inches (10.16
centimeters) wide. Could you tell me how I can replicate the entire case
that you have, and I'm especially interested in the SMA to SO-239
connection. Is the connection hard metal or cable, or what?
I sure want to duplicate the case and connectors like you have shown.
Thanks,
