I have generally seen that if you go by the Ecap data sheet say: 2000hrs @
105 degrees C. T
Then if you are running at an Ecap case temp of say 65 degrees C; the MTBF
works out to be about 32000hrs; if the case temp is 75 deg C, the MTBF is
16000hrs and so on. MTBF generally applies to 50% of

In context with the boresighting issues, I think that you are probably
referring to the hemispherical arc (with a rotating centre table), which is
generally used to model ship borne HF antennae.
The other technique could be to boresight the antenna (with a pneumatic
cylinder) once the

My interpretation of the above, and it is only my opinion - please
feel free to differ, is that for ITE with its related sub-categories,
EN55024 supersedes both EN50082-1 and -2. This would indeed
