RF comunnication

Good day to all the community,

I´m searching for a RF antenna for a communication between a water sensor level and a pump.

The water tank is located in the top of a hill, and the control room where the pumps are located are 700 m (0,5 miles) far away.

THe location is far away from the city, therefore there is almost no interference, but there is a forest between sensor and control point.

I was looking at the RF products from this website, but I couldn´t find information about which one suites me best.

The level sensor hasn´t been bought, therefore I can choose between 4-20 mA, 0-5V, 010V output signal. I can choose the one that suits me best.

I was thinking about using 2.4ghz transmission

Hope someone can guide me with this project.

Best regards!
