I’m new to RF equipment, so I’d like some guidance on antennas and SDRs.
I’ve got an SDR doing ADS-B tracking using the RTL-SDR dongle, with it’s included dipole antenna and the ADS-B LNA. I’m considering getting the FlightAware 1090MHz antenna. Is this just an antenna? As in, does it have any electronics in it that will need DC bias voltage?
Second, would getting the Flight Aware Pro Stick Plus yield any improvement over the RTL-SDR + LNA? From what I’m seeing, it might be a degradation, as the RTL-SDR’s LNA has a 27dB gain, while the Pro Stick Plus’ gain is 19dB. However, I’m not sure if there are other factors to consider.
Thanks in advance for any advice.
