Description

RadioJOVE Terminated Folded Dipole (TFD) and FSX series spectrograph systems

The terminated folded dipole (TFD) array with 24 foot (7.3 m) elements is designed for a wide bandwidth, from 15 to 30+ MHz, for HF band radio astronomy. This array has proven very useful for observing emission from Jupiter, the Sun, and other phenomena present in the upper half of the HF band. There are two versions of the TFD - a 4 element (24 foot each) and an 8 element (30 foot each) variant. AJ4CO has the only operational 8 element TFD. Both the 4 and 8 element versions are dual polarization phased array antennas covering 15 to 30+ MHz. Dave Typinski is the technical contact for the TFD array.

The FSX series of spectrographs are more or less functionally similar. The main difference is that if there is an "S" at the end (like FSX-8S) these are polarization switching units while the FSX instruments are single polarization instruments, all models operate from 15 to 30 MHz.

The FS200B single polarization spectrographs were developmental instruments used at the University of Florida Radio Observatory (UFRO) and Windward Community College Radio Observatory (WCCRO). After the demise of UFRO that instrument was moved to the AJ4CO facility. It covers the same frequency range (15-30 MHz) but uses different circuitry. Richard S. Flagg is the technical contact for the FSX series of spectrographs.
