Designed for noisy radio frequency (RF) environments to help isolate both 1090 MHz and 978 MHz ADS-B signals. Combined with our Pro Stick SDR dongle it will allow you to create an ADS-B receiver to track aircraft up to 250NM away.
1090 MHz ADS-B/Mode S Filter
SMA Female to SMA Male
Passes range 980-1150 MHz
Reduces RF noise, increasing number of ADS-B/Mode S messages
Ideal for RTL-SDR USB Dongle receivers like PiAware
I purchased this to knock out any front-end overload on my rx and the first thing I did was sweep it with my service monitor and it looks great just as advertised it drops off sharp below about 970mhz to around -55db and above around 1100ishmhz again around-55db of reject and the pass looks really flat in-between those two frequencies at -1.4 to -1.8 db of insertion loss, not bad for a filter.

Added filter to improve ADS-B reception
Added this filter to an external antenna (12dBi gain omni) and it seems to have improved the performance of my receiver (along with dynamic gain adjustments). So far, so good.

Good attenuation
Filters unnecessary bands to focus on wanted frequencies. Good product.

Good item. Works in high RF areas.
I installed this on a high gain antenna that was in the immediate area of two HF antennas (100W) and VHF/UHF high gain antennas (110W) and didn't see much degredation. Just remember, there is no substitute for good antenna cable and a location that is generally free from noise. I wish I could do something about the mountains nearby too.
