Review on 📡 Electrodepot 433 MHz Unity Gain Omni Antenna: 6" with Magnetic Base & Male SMA Connector - 50 Ohm Impedance by Josh Reynolds

The magnet is either good or weak and a strong wind knocked it over so I had to use wire to keep it from moving. But it increased the range of my Mighty Mule opener. It's hard to say how much. My range varied from 6 feet to 20 or 50 feet depending on the number of sunspots on those days. But overall I am satisfied with this antenna. My Mighty Mule works thanks to this antenna and not in a dumpster.
