MISCELLANEOUS
Manufactured:Japan, 2022-202x
Additional info: This system consists of a controller in IC-705 style, connected to an outdoor
IPX5 waterproof RF module via LAN cable, adopting PoE technology. This
effectively eliminates coax cable losses. For ultimate frequency accuracy and
stability, the system is controlled by a 1 PPS clock signal from a built-in
GNSS/GPS receiver.
