AN/TSC-156D: Protect Phoenix Antenna Assemblies

Dear Editor,

During a recent communications exercise (COMEX), we found that three (3) of our AN/TSC-156D Phoenix tactical satellites had identical, quarter-sized holes in the antenna assemblies. We discovered that operators were stowing their antenna assemblies with the lightning rods in the UP position and not in the STOW position. Then, as the antennas were taken down, the lightning rods would puncture the antennas.

The proper way to stow lightning rods is in the horizontal position. This configuration ensures the antenna assembly has the proper clearance and prevents damaging the antenna assembly.
