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

With no means to measure the SWR, and Tuning of the "Antenna-System",
your plan would probably have very dubious results,
but it could possibly work well enough to do the job needed,
but only by a lucky "accident".

When You attempt to alter the Antenna, "all bets are OFF".

A better plan would be to not alter the Antenna in any way,
then mount the Transmitter, ( with Antenna still attached ),
in a plastic box on top of the pole.

The extra elevation of the Transmitter, ( along with it's integrated Antenna ),
above ground-level,
will increase the coverage area substantially.

Thanks.

Some devices have pads for a coax socket next to the antenna. But that means adding a connector, cable, and antenna, which adds complication and cost and weatherproofing. That might be worth the effort if you need a directional antenna for longer range, but if it works OK now, just weatherproof it and put it on a pole.
