How about aluminum 'duct' tape for shielding? What are the differences compared to copper tape? Mike C.

Here is the one I am using for my H4. https://www.amazon.com/gp/product/B07CG4691Y It has some padding, and pockets for cables, etc. ...Bob / AA2FD

Self-adhesive copper foil may be alternative that offers better shielding. I have used it on many plastic enclosures. I can solder bridge between sheets to cover areas wider than 4 inches.

I like your solution, but how do you access the controls on the Nanovna? It appears they are all inside the case. What is it that I'm missing? Thanks in advance. Jim KC3DPO

Jim, I've used that tin oxide for shielding of a few large products. Visibly it's transparent which was a requirement. But I've found it's only marginally effective, but it's better than nothing. Dave

in practice, touch screens usually have a transparent conductive layer on the top (indium tin oxide is common).? Or the actual LCD display has an ITO top electrode, and the touch screen is resistive

And how are you going to "shield" the touch screen? And those "thin traces" to the SMAs? They are likely printed against a ground plane in the layer beneath the surface layer and likely adjusted in

Here. I look at it this way. 10% in transmission (power) corresponds to a transmitted E field 32% of the incident E field. A surface that reflects 90% of the incident power still allows 30% of the E

I'd call 10dB in power and 20dB in E-field poor shielding and 0.4 dB loss on reflection very good for an antenna. You could take another example, 50%/50%. That's 3 dB each way. We could argue ad

Using your numbers Lou, I would not call a 20dB reduction in E-field "very poorly as a shield". The most difficult part of using any spray is getting it in to tight corners. I''ve done "touch up" on

Harbor Freight sells a small case like that as well... 73, and thanks, Dave (NK7Z) https://www.nk7z.net ARRL Volunteer Examiner ARRL Technical Specialist, RFI ARRL Asst. Director, NW Division,

The following is a copy of my post of 30th August 2021 which illustrates my solution to the enclosure/connector issues: The attached pictures show my solution to the SMA issue. 1) BNCs match all my

I disagree with that blanket statement. The requirements and performance measurements are very different. There are a lot of variable, but for example, a surface that reflects 90% and transmits 10% of

I bought a MAX002S IP67 case from Amazon last night and it turned up this morning. It's absolutely perfect for my use and is waterproof too. Everything I need fits in, I've put the USB-C to USB-C

The marker data on the left does update correctly. I am unable to see the markers in the chart windows. Ed

Hello all... I'm not sure this is the right place to ask this, but did not find any other. I downloaded the new version (0.3.10) and I no longer have the markers in the chart windows. Version 0.3.9

copper foil tape is readily available, has a conductive adhesive, and works quite well. It's available in a variety of widths. Thin copper foil is also available - it's used by people making electric
