We apologize for the long delay to repair it caused by a series of failures. The back-up receiver was also faulty and the antenna had to be repaired as well since after the receiver was fixed it was found that water was sitting inside the antenna. After the antenna was repaired and installed it was detected that the antenna height contained in the station information form was wrong, being the correct one 0.107 meters instead of 0.120. This afects the approximately six months of data provided from the installation till the failure. The updated station information form is included below.
