[TowerTalk] Raising Mast

[donovanf at starpower.net]

Bob,

The cast aluminum Ham 4 lower mast mount  W I L L   F A I L  if you install a 10 foot steel mast and beam above it.

You can mount a long mast with a top-mounted beam on a Ham 4, but only
if the Ham 4 is mounted inside a tower, and the mast is supported above
the rotator.
