Hi Al,
   The configurations group probably need to be aware of this. (I don't
have a good distribution list to hand - could you please forward this to
anyone who might need to know?  Thanks.)

		Cheers,
			Darrel.

Subject: Transporter approach side

Hi Darrel,

This is to confirm what you surely have heard already from Jeff K: We are
working on the assumption that you will be able to approach the antennas
from any side with the transporter. However, once the array configuration
has been chosen, we may decide only to approach a given foundation from one
or more preferred directions to save on road costs. However, this should
not prevent you from assuming that pickup from any side will be possible
when you lay out the array configuration.

There is a small snag. In the antenna specs it is indicated that the base
can only be rotated +/- 30 deg while on the transporter. We believe that
both the Vertex and the EIE antennas will be able to rotate the full angle
so there should not be any problems. However, at least for the EIE antenna,
we do not want to change the specifications at this time for contract
handling reasons.

Rgds
Torben
