My setup consists of FlightAware Pro Plus (Blue), FA 1090 Mhz Filter, FA 1090 Mhz antenna, LMR400 cable, Raspberry Pi Zero W. I was on the fence about adding the filter or not since the blue dongle allegedly has a built-in filter, however I’ve experienced better results also using the filter and found it worthwhile. Now I am considering adding an LNA. I’m looking at a SMAKN LNA from Amazon:
amazon.com/SMAKN-Ultra-low- … +noise+lna
Anyone using this LNA (or any LNA in general) that can anecdote their experience and improvement? My antenna is ~50’ AGL on my apartment balcony. I’m seeing decent reception from the East, however I would really like to get it above the roofline to get more omnidirectional reception. It’s on the building wall blocking the W/NW, plus the terrain has a hill in that direction. Eventually, however, I’ll get it above the roofline. Until then, I’d like to see what type of improvements an LNA may add in all the other directions. From my background (SATCOM and Microwave Troposcatter in the Air Force), I’m assuming the best place to have the LNA would be directly connected to the antenna versus having it between my filter and receiver (dongle)?
I’ve experimented with different gain values using rtlsdr-gain and just leaving it at -10 for AGC was optimal.
