There is no greater bang for your buck to upgrade a LoRa Meshtastic Device. *** NOTE PLEASE SHUT OFF YOUR DEVICE BEFORE INSTALLING *** *** DEVICE POWERED ON WITH OUT ANTENNA WILL COOK YOUR DEVICE *** The stock antenna on my LilyGo T-Echo was 7.87:1 SWR and 24.84 ohms resistance. I was barely able to pick up nodes on the device - even in optimal high ground locations. When I upgraded to the Tenmory 3dbi antenna I gained SIGNIFICANT IMPROVEMENTS! The Tenmory 3dbi in a Straight - Vertical configuration is a 1.28:1 SWR and 40 ohms. Very close to an almost perfect antenna and fairly wide bandwidth across 900MHz to 930MHz. See pics. When I tested it in the 90° bent Vertical position it saw a degradation of performance. 2.9:1 SWR and 125 ohms. Still better than stock but I wouldn’t run it that way. Keep it straight. You can see the joint where it bends in the photo. I keep it in that position as a stress / strain relief when I put the device in a pocket. That way the joint bends before the unit breaks. Very well made. Great engineering. Easy to install if you power your device off. Fantastic results. Hitting some devices at 50+ miles direct.

Excellent quality. Great price! Mandatory upgrade for the stubby antenna meshtastic kits come with.

My field hands continue to break these through various means and these are a nice alternative to getting them from a survey store. they work perfectly and are much cheaper as well

I've bought and returned 9 different antennas for the 915Mhz range over the past month and will not be returning these. Most other antennas were tuned outside the spectrum they were advertised for or not tuned at all (4-8 SWR from 1htz to 3Ghtz). These ones came in at 1.2 SWR across the intended spectrum when straight and 1.4 when bent on both antennas. I'll most likely order more when I finish building my next boards.
