If you own one of the original NanoVNA or the TinySA with the 2.8 inch screen there is one small problem, it either has no case or a plastic case. For the TinySA this becomes a problem when you live next to strong transmitters. Right up the hill from me is a strong pager transmitter and even with the inputs terminated with 50 ohm loads I see the signal when it comes on. I did some research and found this seller on e-bay that sells metal shells for the nanoVNA. Since the TinySA has the same footprint I bought a case to see if it will fix the problem. I had to scrape the paint of the mounting studs and the case screws to ensure a good ground connection, and since it is designed to take the place of the front panel for the NanoVNA it uses those screws ...so they will be missing when the case is used for the TinySA but lucky I have ample of M2.5x5 screws so I had no problem. Does it solve the issue? Yes it does, it even solves the ingress from my 900Mhz beacon I run at the house. Well worth the money. All that is needed now is to get a few white rub on letters to label the inputs and I will be ready to go. If they are out of stock, just wait a couple of days the seller replenishes the stock regularly. It took about a week to arrive.
