Hello,

Sorry 1) if this is wrong place 2) Dumb question.

I am working on smart irrigation project, I have Arduino connected with 4 sensors and 1 actuator, Arduino collect data and send to ESP32 using Reyax RYLR896 Lora Module connected to it.
I keep all PCBs in one waterproof box, but this cause network loss with other Lora node, so I decided to remove antenna from RYLR896 and install it on tall pole and connect it to RYLR896 by single wire, will this, work?

This is original RYLR896

This is what I planned to install antenna

Yes, the wire has to be co-ax, you can't use normal wires. The co-ax needs to have its shield connected to the module ground as close as possible to the antenna connection. I would suggest RG174 cable is suitable.

You will undoubtedly get better results by using a proper external antenna. The helix is suitable for close range work but you would get far better coverage by using a purpose made antenna for the frequency you are using.
