Information request for a remote installation of a Colibri.
1) What is the maximum rf input signal level (dbm) that the rf input of a Colibri rx will accept without damage?
2) Is there input protection in the Colibri to protect it if the maximum rf input signal level is exceeded?

73 and HNY

Received the requested information from Roman.
Answers below:

1) Do not exceed max RF input signal level ~1V (RMS) ATT -20 dB ON; 100 mV (RMS) ATT 0 dB.

2) There is a 1kOhm 2W resistor for slow discharge electrostatic voltage.
There is no protection diode.
