I have tried replacing a small 0dBi whip antenna with this antenna, reportedly 3.5dBi. OMG it was so bad - the stub antenna was picking up 903MHz LoRA packets with RSSI -109. This new antenna doesn't even receive packets well enough to pass CRC checks, which means the RSSI is below -124. So definitely not somewhere around 3.5dBi or worse than a tiny decent whip antenna.
