Snow on the LBA field

Over the last couple of days, we've reported how snow affects the RF performance of the LBA aerials. Today we have some more photographs from #L33 and #L34.

Just a bit deeper here. Note how this aerial has its wires partly
covered, where the others in the background have their guys and
elastics still visible above the snow line. (Photo: D. McKay-Bukowski)

There was about 20 cm of ice along each
receiver wire. (Photo: D. McKay-Bukowski)

Another image of the iced up wire. The snow depth is
approx. 70-75 cm. The HBA array is visible in the
background. (Photo: D. McKay-Bukowski)

Digging down to the ground plane. Notice how the aerial
is leaning. This is due to the ice tension on the wires,
guys and elastics, causing distortion of the LBA aerial.
