Based on questions from users and realizing not everyone is aware of how to safely protect a sensitive Spectrum Analyzer like RF Explorer from strong RF fields, I wrote down an article with a few suggestions and background info you are suggested to read in order to keep your device safe for years of use.
Please check here.
The most important suggestion is to keep your RF Explorer without antenna when you store it or if you have to go across strong field areas like RFID points in shops, X-ray scanners in airports, etc.
Any question let us know. We can add more info if required.
