One day people met on the summit asked me (joking of course): is it pegasus investigating system ?
From that time if somebody ask me (showing my antenna) what is it ? I use 2 options:
- if the people looks heavy understanding jokes I answer: this is antenna for radio communication
- if the people seems happy/funny I answer: this is pegasus installation.
The second option usually brings me and other people a lot of fun
