Mini case for LNA4All low noise amplifier for RTL-SDR radio

thingiverse

If you play with RTL-SDR dongles, you may have heard of the LNA4All low noise amplifier, which goes between your antenna and the dongle. It's a tiny little device that can vastly improve signal reception, especially with the cheapie antenna that comes with the dongle. Since it comes as a bare board device, I designed this little case for it. I consider it a work in progress because I have not even powered-up the LNA4All yet, so don't know if it generates heat, for example, that might demand some cooling holes or other mods to the case. I'll figure that out as I go along. The LNA4All requires a 6-12V power source. I figured that, for now, I'll just stick this little guy onto a 9V battery or 4-6 AA battery pack for the juice it needs. Later on, I might redesign with an integrated battery compartment... or perhaps a case for the RTL-SDR dongle and the LNA4All, side by side. But a little experimentation is in order first. BTW, the little cutout at the top left of the design is for the power wires that go onto the solder pads just below that slot. I added a vented-lid version as well. Will hopefully test them soon.
