Since my last thread, my setup received some much needed upgrades.
It is now as follows:
RPi 3B+ —> FA ProStick Plus —> FA ADS-B 1090MHz Filter —> LM400 Coax —> FA 26" ADS-B antenna
The cable connecting the antenna to the rest of the equipment is 50 ft long and I feel like that is restricting its abilities. I ordered an Uputronics ADS-B Filtered preamp and had a few questions about installing it:
It’s powered either by bias-tee or the mini-USB port on the side.
Does the FA ProStick+ dongle supply bias-tee power or will I have to power the preamp externally?
My Raspberry Pi and my wireless access point are inside the house, protected by a small UPS in case of a power outage.
The antenna is on the roof, far away from the RPi. There is power on the roof, but there is no UPS, so if the preamp was powered through it’s mini-USB port from the roof power, and there was a power outage, would my RPi continue to receive data with reduced performance or would it not receive any data at all due to the preamp not running from lack of power?
The Uputronics preamp has SMA on both ends. My coax cable has SMA on one end (the side that currently plugs into the FA filter), and N-type on the other one, which is what plugs directly into the FA 26" antenna.
Since I plan to install the preamp right behind the antenna, I would need an N-Type to SMA adapter or cable, and then another SMA to N-Type cable to connect the other end of the preamp to the antenna.
How much would adapters/cables affect the performance of the preamp in this situation?
How much of a performance gain would I be looking at if I just installed the preamp inside the house? If I were to do this, would the preamp be installed after the FA filter, as shown below:
RPi 3B+ —> FA ProStick+ —> FA ADS-B 1090MHz Filter —> Uputronics preamp —> LMR400 Coax —> FA 26" ADS-B antenna
Or before the filter?
RPi 3B+ —> FA ProStick+ —> Uputronics preamp —> FA ADS-B 1090MHz Filter —> LMR400 Coax —> FA 26" ADS-B antenna
Would really appreciate your help.
