However, there has been an additional complication: the original LBA field site is simply not stable enough to take the LBA array as originally planned. This has forced a rethink but, in turn, this has actually allowed us to come up with a better solution, that we could not have foreseen before the HBA was built in 2011.
The plan now is to locate the LBA to the south-east of the HBA. This gives a large number of benefits. Firstly, in terms of deployment, this is the easiest area to work with. There are no ground stability issues and there are no problems in terms of vehicle access, which would be the case on the tundra. The new area is also (mostly) in the shadow of the HBA, thus affording additional protection. It is on the raised mound which should also help keep snow levels down.

The array area is shown in the following diagram. At this stage the exact placement of individual aerials is not shown, but we will discuss this in another post coming soon.
