Hi Guys,

I have been giving some thought to stacking a Hygain 5L 105CA (10
meters) and a Hygain 5L 155CA (15 meters) as follows:

T2X rotator in tower (3' below the thrust bearing).  105CA just above
the thrust bearing and 155CA at the TOP of the mast 10' above the 105CA.

As you know the 105CA and 155CA are NOT balanced at the boom to mast
clamp so there is additional stress on the mast and rotator.  I will be
using a 14' carbon-moly mast.

Any thought on whether or not this arrangement will tear up the T2X or
should it handle everything ok?  The boom on the 155CA will be "guyed"
to support it.

The tower is 100' and is located at a high point on a hill (elevation
790' ASL) that gets VERY windy and in the winter gets a fair amount of

Your thoughts and comments appreciated....
