Rycote Stereo Windshield size AG. see manufacturer for configuration details
The standard (basket) windshield shows up to 25dB windnoise attenuation at 35Hz while giving almost no signal attenuation. Adding a Windjammer will give an improvement of some 10dB at LF - 35dB. The attenuation of the Windjammer is approximately 5dB at frequencies above 6kHz although this will increase if it is damp or allowed to get matted. Overall this combination gives the best performance of wideband windnoise reduction against signal attenuation.
