Thanks for this ... let me throw a monkey wrench into the works ... price,
rotor capacity, and tower space are issues.

I cannot afford several thousand dollars of antennas to cover
6-10-12-15-17-20-30-40m.  I have the KLM34XT for 10-15-20.

I have a Tailtwister T2X to turn the KT34XA, I am told that will about max
it out here in New England given ice and wind.

The KT34XA will be at the highest point on Tower 1, about 70 feet.

On Tower 2 (35 feet plus mast) I plan to put antennas for 2-6-12-17-30-40. 
The 26 foot boom Sommer XP808 I am looking at should handle all but 2m! 
I'll take the suggestion read here and put a 2m beam above it to help with
adjustments -- I presume I will need at least a Ham IV to handle that ...
or do I need another T2X?

Know anyone in New England looking for a KLM KT34XA reasonable?  I'm think
I am only going to use one.
