For
over a decade SeaSondes operating between 24-50 MHz frequency band
have an antenna system that co-locates both transmit and receive
antenna
elements atop a single mast. Recently this capability to operate
with a
single-mast antenna system has been expanded to include lower frequency
bands
down to 12 MHz.
Though a traditional two-mast antenna system – one for transmit
antenna and
one for the receive antenna – is already extremely compact
by conventional HF
radar standards, a single mast antenna system represents a critical
practical
convenience when installing in congested urban areas, on oil platforms
or atop
other manmade structures.
The first 12 MHz combined antenna systems were purchased by Scripps
Institution of Oceanography (SIO) for use on oil
platforms in the Gulf of Mexico. Shown in photo are CODAR company
President Don Barrick and Tom Cook of SIO
with the first 12 MHz combined antenna. This unit was delivered to
SIO in 2008. |
