== Current Status ==
== Current Status ==
* We have some parts but we need but quite a lot of stuff needs to be bought, built or fixed (see Kit below).
* Currently in purchasing and refurbishment stage as well as final planning on assembly and connections
* We need to have proper discussion with other interested parties.
 
* We need to come up with a final design of what will go on the antenna array and how it will be organised.
== Task List ==
* We need to at least seek provisional permission for the antenna array to be erected ,so we are aware of any additional things we need to consider.
