We have also visited the back of the antenna and in particular the receivers cabin roof for possible installation of the NIKA-2 electronics. Space available is 80cm (H) x 200cm (Width) x 100cm (Depth). In order to have enough space to work, we will use a maximum depth of 60cm. The total COAX cables length if this solution is chosen is 6-8m.
