Satellite dish for Astronomy project. (Bloxwich WS3)

Satellite dish 'over 1 metre' in diameter, as anything smaller isn't able to pick up radiowaves from our MilkyWay.
  Old or not used, anymore dish. Would be put to amateur astronomy project, which means we add bits onto the dish to pick up the 1420Mhz radio-waves. Ideal if still have the arm attachment and rear brackets. We add on various bits to convert to a Radio-Telescope and hopefully find E.T. before they find us lol (j/k)
