I’m trying to find an amplifier for LoRa modules.
I have just bought and used modules T-BEAM V1.1 and the rank of connection is about 3-4 Kms in the field.
I have also found new 868MHz antennas, 550mm long, but I need more voltage and intensity maybe in the circuit to increment the rank to at least 20 Kms.
My purpose is to create a node or big mesh network between devices in a range of 20km.
Does anyone know something about an amplifier to use it with Meshtastic devices??
I get 20km by using a $7 moxon antenna on one end and folks have gotten >100km with a moxon on both ends. Check those out.
Are moxon antennas omnidirectional?
I have read about them and the distance is amazing (almost 100 Kms) but it seems to be needly directional communication.
Do you know something about omnidirectional antennas for 868Mhz T-Beam devices?
If you’re looking for a good omni directional, consider reputable sources like digikey… there are many on ebay or other sellers that are questionable.
Look for collinear antennas or sometimes called fiberglass antennas.
maybe this helps
But it is important to remember that the best amplifier is the antenna.
Here is my post from another thread today regarding an amp I am testing:
I have been going the expensive route, geeze I am going to have to try these things.
