I need to order severals antennas, and I worries about the performance of the antenna. So, I have a couple of question.
More the antenna is big more the range will high? (I mean; more my node could be far from my gateway?)
Which are the criteria which make a high quality antenna, the size, the imedence, dB?
Here are the 3 antennas, I already have
I would like to buy some but from a shop in my country and I can find that antenna and antenna with the mention of LoRa. I wander, if I can simply order a GSM antenna or use some I already have. Is the LoRa antenna are different the GSM antenna.
Here are some idea I have:
Does a roof antenna is recommanded as this one
Do the following are more recommandate (dB is higher)
Many thank for your recommandation
