2.5 dBi SMA Male 915 MHz or 868 MHz (choose variant) soft flexible whip antenna is an omni-directional SMA Male dipole antenna with 2.5 dBi peak gain. The antenna is 7.8 inches tall and and can be completely bent as shown in the photo without internal damage. Suitable applications are as a factory replacement antenna IoT hardware and Mesh networking devices. Flexibility is perfect for handheld radios like LILYGO T-Echo.
Nanometer testing note: Nanometers don't identify the parameters of resistance and capacitance of the soft antenna structure properly. Use of a network anaylzer is recommended for correct VSWR testing.Test completed using Agilent 8753d network analyzer will show accurate SWR pattern. Using a nanometer is not advisable for soft antennas.Get the right connection:SMA Male (this antenna): inside threading, center pin

Because gain cannot be easily measured by the end-users, we have seen similar antennas marketed aas higher gain. ALFA Network has been making antennas for over 17 years for WiFi, 4G, and other applications. Our 915 MHz antenna are listed with actual specifications. You also do not want extremely high gain as your path will be very narrow and miss other hotspots.
I see similar looking antennas online that say for 600 MHz to 2700 MHz, is a wider frequency spectrum better? Antennas with a focused spectrum will have better performance on that band segment vs antennas with very wide spectrum. We would not recommend using antennas that are also WiFi 2.4 GHz compatible with your mining equipment. This antenna has a frequency range of just 900-930 MHz to give you maximum performance.
