Hi all,

My websdr is located in Heppen, very small town in Belgium, located between Eindhoven and Aachen.

Antenna is a 54M Longwire that I used to build for 160M band transmissions, but I do not use it much.
I hope you see the wire going up way high to about 25M+

So it's connected to the Websdr with an MFJ SDR-switch, jumpered to disconnect when the antenna receives too much signal....yes you can do that, then it auto-protects ;D

That's how I build my WEBSDR. The reason it's inside the computer is that a computer-case has an airflow, so better cooling for the receiver. And on top, less problems with RFI/EMI etc.
