I am going to setup an IC880A + rasperry pi gateway following this guide: https://github.com/ttn-zh/ic880a-gateway/wiki
I’m doing research on the influence of environmental parameters on the radio signal. Therefore I would like to analyze the attenuation of the received signal beyond RSSI and SNR which is how I found out about the SDR-devices.
My knowledge about radios is limited to what I have learned from reading the forum and watching videos on youtube.
So here my very basic question:
Is it possible to connect both gateway concentrator board and SDR-USB-dongle to the antenna?
If yes, how?
My concern is that the gateway uses the antenna to send waves while the SDR “listens” on the antenna. I read about splitters and taps (here), which can be used to split the signal into two receiver cables. Can signals sent by the concentrator still reach the antenna through a splitter/tap?
Thanks in advance for your answers
