Which board to use with LoRa antenna

[ponpon777]

Hey guys,
I need to send data from a sensor connected to an arduino module to an esp8266 through LoRa protocol. The esp8266 will then send data by WiFi.
I tried with 2 different LoRa module but I couldn't go very far (5m to 150m).
I read a bit on this and I know there are a few things that can be improved (interference...).
My questions are (please forgive me if they look stupid):

• In Europe, and especially in France, I guess I can use both 433 and 868 MHz, but would I have better results with 868 MHz? (my first attempts were with 433 MHz, the only one I had). One of them was this one:

• I'm trying to order a LoRa module (RFM95 I think should be a good choice) where I would be able to connect this antenna :

I found this one but it is for 433 MHz

TECNOIOT 2pcs SX1278 Lora 433MHz Ra-02 Wireless Spread Spectrum Transmission...

Can anyone help me on this, please.

Thanks a million

Do you have clear line of sight?
Antennas should be used both at sender and receiver. Internal (printed) antennas are far less efficient.
Put the antennas straight up on both sides.

When I did my tests, not really. For my future installations either. 150m is not bad but I'm trying to see how far I can go.

That I know. Sorry, I should have write that but I read a bit about usage and design. What I want to know is which LoRa module (868 MHz) could accept an iPEX connector for the antenna I showed. Or is there another to plug this kind of antenna? Or is there a better couple module / antenna I could use?

Thanks!

Sorry, I don't know...
But 1 km should be doable, so I thought something might be wrong with the basics...

It think you mean a pair of units, not just one.

Yes of course. Sorry for not being clear.

Basically, how to connect this...

with this...

Or, what are the other options?
Except this one...

Thanks
