Dorne Margolin Antenna for Ashtech Receivers
--------------------------------------------
The current antenna diagram file antenna.gra to be found at the IGS
Information System contains the following diagram for the Ashtech
Choke ring antenna:

Recently I got from Polish colleagues a copy of a drawing (which came together
with their antenna, model 700936) containing different numbers (rounded to the
millimeter):
-----

<-- 0.379 -->
My questions: Is anybody using the original values of the first diagram
in their data analysis or can we replace them by the obviously "more official"
ones of the second diagram?
