This antenna "works", but not very well. It has a good SWR at 923 Mhz (especially when mounted on a ground plane) but at 906 Mhz (US LongFast for meshtastic) the SWR was up at 1.6 or 1.8. More importantly, the stock indoor antenna that come with my WisBloc Tap performs better than this antenna. [It can make connections that this antenna fails to do, and when they can both reach the same node, my stock antenna made a better connection. The ONLY advantage of this antenna is the 10 ft 3m coax cable and magnetic mounting base, allowing you to potentially place your antenna outside while keeping the transceiver inside. An antenna outside will beat the inside antenna, so this will be an upgrade. Unfortunately, the magnet isn't terribly strong, and the antenna itself is very heavy (it feels like it is made from a single piece of metal). It will just barely hold itself against a vertical surface, but if you put the sightliest amount of tension on the cable it falls off. It holds fine on a horizontal surface when gravity is helping it out, but due to the weight and lever arm nature of the antenna, I'm worried that if it was on a vehicle that was accelerating or decelerating the antenna would fall over, and roll/slide off. So it's not an upgrade over my stock antenna from a signal standpoint, and the magnetic mounting system isn't strong enough for vehicle motion. About the only good thing I can say about this antenna is that you can potentially mount it outside, which will improve your performance over an inside antenna. Instead of this antenna, I have two others that work much better which I reviewed here: https://youtu.be/maxwExTnSCs
