This is a set of a booster antenna and signal distributor for B-band wireless microphones (specifically 470-960MHz, so it can also receive white space frequencies) sold on AliExpress. In these noisy times, I think this is an essential set for efficient reception. Operation has been confirmed. The antenna has some scratches as it was used on location. The distributor is in fairly good condition. Please check the photos for the condition. If you have any questions, please ask.
