Work completed:
Installed electronics box 30477
Installed RMY aerovane with Belfort base
Installed Antennax antennae
Removed ADG, ADG radiation shield and ADG enclosure
Installed new ADG to attach to the 30477 electronics box
New height to bottom of:
Lower temperature sensor: 20"
Junction box: 41"
ADG: 43"
Solar panel: 49"
Electronics box: 77"
Solar panel: 154"
Antennae: 164"
Boom: 175"
Received 3 successful transmissions.
A few notes:
* The old style antennae was left on the boom with the electronics box end of the cable taped off
* The Antennax antennae was attached directly to the tower as done at Sabrina. This caused close clearance with the aerovane, but it was verified multiple times that there is sufficient clearance.
* The old ADG enclosure had a battery cable hard wired inside. In order to remove the enclosure, this cable needed to be cut. Dan and I did not have a shovel to try to dig up the battery box. The cut end of the battery cable has been covered with tape and taped to the tower.
* The cable to the lower solar panel followed the tower down into the snow. Does this go to the battery box that powered the ADG enclosure? If so, is there a problem that this is still connected and the battery box cable has been cut? |
