The frequencies that the S-6 gives you should be near the FOT line for the time periods that you plan to communicate on. If the frequency plan is not executable, then no amount of dutch longwire stuff will work.
The freq plan must be workable. Unfortunately, most freq managers are bean counters.

I think this may be our biggest challenge. I'll reserve judgment on whether we will get a workable freq plan for now, but I am not optimistic.

Whats the goal here, to conduct a commex or a hide with comms?

This is meant to be a COMMEX. The PRC-150 is still relatively new to our unit, and I believe that this is the first time we are attempting a skywave shot with them. With the right preparation and planning, this could be a great way to introduce our younger and more inexperienced soldiers to building antennas and getting good HF comms. Without good preparation and planning, well...
As an aside, I believe the "Dutch" long wire is just some strange nomenclature specific to this unit. Who knows how these things get started.
