===============
I have just seen a new geodetic antenna bought out by Trimble. The
dimensions of it are slightly different and I have included them
below. (These are the official Trimble dimensions)
Trimble Geodetic L1/L2 Compact with removable ground plane
----+---- <-- 0.0625 L1/L2
/ + \
++----------------+-----------------+-----------------++ <-- 0.0591 TGP
++---------------+-------------------+----------------++ <-- 0.0556 BGP

+------x------+ <-- 0.000 ARP=BPA
<-- 0.467 --> NOTCHES
<-- 0.483 --> EDGE
The horizontal dimesions are the same as the 4000SST L1/L2 but the phase
centre appears to be about 6mm lower.
I have included this antenna into the antenna description file "antenna.gra"
and under the name of TR GEOD L1/L2 COMP into the table of receiver and
antenna names "rcvr_ant.tab" in the IGS CB Information System.
