I've been wondering for some time now why amateur operators don't build
their Yagi antenna's
so they can be raised and lowered about 10ft in addition to being
rotated.

The answer is because it isn't really necessary in most cases. If you
optimize your antenna for low-angle DX signals where you really need
the gain, there will still be significant radiation at high angles,
which are generally closer to you and will have stronger signals as a
result anyway.

This might be significant enough for a QRP operator to want to do it,
but at the 100 watt or higher level, you wouldn't gain much. Pun
intended. :-)
