Wideband antennas for VLBI were developed and reported in this poster.
Wideband feeds and OMTs were newly developed to upgrade Kashima 34m antenna and small portable VLBI stations named MARBLE of NICT.
Our project, named Gala-V, uses 3.2-14.4GHz with NINJA feeds and 6.5-15GHz with IGUANA-H feeds.
Wideband geodetic observation, methanol masers observations of 6.7 GHz and 12.2 GHz in same time and other various wideband radio astronomical observations are capable now with these antennas in Japan.
