End of EMBRACE

Submitter: Jan-Pieter de Reijer
Description: With a little sadness are we taking this test antenna apart. At the start in 2008, we thought that we would need this "proof of principle" for only one, maximum two years of operation.

Now the third Midden-Drenthe temporary building permit will expire end this year, and with no longer active users for this system, the decision is made to remove the antennas, radome and Faraday cage. On the photo is Peter Gruppen, separating the different types of materials, to enable an environmently friendly disposal.

The Westerbork Electronic Multi Beam Radio Astronomy Concept, EMBRACE, was a prototype of the aperture array concept, built in 2008. See also the daily image of 23-05-2008. In Nancay (Fr.) is a second EMBRACE antenna, but also no longer in operation.

EMBRACE had a frequency range of 500-1500 MHz, with single polarisation. The 17x17m radome is made of 19cm expanded polystyreen. The 20x22m platform is made of 118 2x2m concrete tiles.
