NOTE: The RF300-series transceivers are still available for customers who already own RF300-series transceivers, but for newer radio customers, the RF320-series is usually a better choice.
The RF302 is a DRL UHF radio transceiver for customers who will have an FCC-assigned frequency in the range of 450 to 470 MHz. It's programmed to an exact user-specified frequency by Campbell Scientific using special software.

NOTE: The RF300-series transceivers are still available for customers who already own RF300-series transceivers, but for newer radio customers, the RF310-series is usually a better choice.
The RF302 is a Dataradio 3412-510 UHF radio transceiver for customers who have an FCC-assigned frequency in the range of 450 to 470 MHz. The transceiver is programmed to an exact user-specified frequency by Campbell Scientific using special software.
Besides the radio, each field station and repeater station must also have an RF500M Radio Modem or RF95(A) Radio Modem; base stations need an RF500M radio modem, RF500B base station, or RF232(A) base station.

It is possible to connect two antennas to a single radio via a properly specified (operating frequency and power handling capability) two-way, 50 ohm RF power divider. One example of this type of power divider is offered by Pasternack. Note that using a device like this will induce additional losses into the system (3 to 4 dB, typically).
