Air band BPF from AliExpress

Hello,

if you are Air traffic listener or Air band avid DXer then maybe you are thinking about the cheap Air band bandpass filter for your wide band scanner. Especially when you are using the wide band antenna on the roof the overloading from VHF FM BC signals is common issue.

Here is what you will get if you order the cheap Air band BPF from AliExpress.

Well, here is what you can expect from this unit in reality. Be note that attenuation is even lower for about 0.4dB due to connected coaxial test cables and all used adapters as it was not compensated in this case.

Check the values and order it only if it fits to your needs, otherwise forget it to avoid disappointment.
