Does anyone know the specs for the FlightAware dual UAT + ADS-B filter? Is it the original filter with a new label? (The part number is the same: PCT-BPF-980-1150.)
From a retailer here in Australia I ordered what I thought would be a 1090MHz filter (which reportedly passes 980-1150MHz) but what turned up was a combined 978MHz + 1090MHz filter - not the same item shown on their website. I’m curious as to what its working range is, mainly because 978MHz isn’t used in Australia for ADS-B related activities.
Although the filter has a male connector on one side and a female connector on the other side, are the electrical characteristics symmetrical? in other words, does it make a difference which side is connected to the antenna and which is connected to the receiver?
Are the filter characteristics available such as center frequency and bandwidth, etc.?
Thank you for your swift answer with link (FlightAware ADS-B filter VNA measurements) to filter plot with some data.
To summarize, the VNA display shows that the BW is 230.99 MHz, the center is 1.0726 GHz.
