Point-to-Point
In this configuration, two radios will be talking to one another. Typical examples
are serial-to-serial communication or peer-to-peer I/O wire replacement
systems. Yagi antennas at both ends increase signal strength, range and reduce
interference.
Point-to-Multipoint
In a multipoint system, an Omni antenna is typically used as the master with
individual Yagi antennas as “slaves” pointing to the “master” antenna for the best
range and signal strength. A typical example is Modbus I/O configuration with a
Radio Modem connected to an RTU master with several I/O nodes as slaves.
When transmitting, a Yagi antenna allows more
transmitted power to be sent in the direction
of the receiver, increasing the received signal
strength. When receiving, a Yagi antenna
captures more of the signal, increasing signal
strength. This also reduces interference.
