They have great OEM construction and compatibility but the performance is poor, less than 2dBi. This is typical for most "flag" antennas. If you are looking for the best gain and can install a 9.5 cm (3.75 inch) indoor antenna, we recommend the following IPEX MHF4 8dBi antenna. https://amzn.com/B08T8F3GDT dBi can be reduced depending on where and how it is placed, but the gain over HUYUN flags is amazing! If the 9.5 cm (3.75 inch) length is too long, the end of the board MAY be cut off. This will decrease performance, but not by much.
