This is one of the earlier radome designs, by Danny van Loon, in 1991. For some time, it has also been used in the Swedish network, but there it has been phased out. 241 0.0 0.0 0.0 0.0 30.0 1996-10-30T14:00:00Z 93243 0.0 0.0 0.0 0.0 30.0 2000-04-27T10:50:00Z 93251 0.0 0.0 0.0 0.0 30.0 2004-03-24T14:30:00Z On 2020-11-20 the antenna cable was replaced, and a new antenna entry is created. Between 2020-11-16 12:00 UTC and 2020-11-20 14:30 UTC the data quality is sub-standard and not considered usable due to the ingression of water in the antenna cable. 726700 0.0 0.0 0.0 0.0 30.0 2020-11-20T16:54:00Z This is the same antenna as the in the previous item, but the old antenna cable (which contained water and was damaged) was replaced by a new cable. To replace the cable the antenna was unmounted and placed back again in the same position, however, very subtle differences in the position on the mast cannot be excluded. 726700 0.0 0.0 0.0 0.0 30.75 2020-11-20T16:03:00Z 1996-10-30 1996-10-30 2018-12-17T15:01:00Z 2020-11-20T16:09:00Z ARP: antenna reference point BCR: bottom of chokering BPA: bottom of preamplifier TCR: top of chokering]]> ARP: antenna reference point BCR: bottom of chokering BPA: bottom of preamplifier TCR: top of chokering]]>
