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.
We’ve brought this antenna into our MESHTAC™ lineup. While the design is semi-common and offered on other electronic sites, make no mistake, all antennas are not equal. Similar looking antennas are often tuned to a wider frequency range, reducing performance on 915 Mhz/Meshtastic. Our antennas are custom designed and tuned specific for Meshtastic and LoRaWAN. Accept no substitute!
Nanometer testing note: Nanometers don’t identify the parameters of resistance and capacitance of the soft antenna structure properly. Use of a network analyzer 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.

Beware cautious of gain inflation- some places arbitrarily inflate antenna gain numbers to appear better than competing products. 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.
