[TowerTalk] phasing verticals

[jim Jarvis]

If there's a reason for phasing at the antenna, it's that storing the  
phasing lines
inside the shack can impact available space.   But it's a much better  
solution than
switching at the antenna, for reasons of phase stability, weathering,  
and simplicity
of switching.

As you know, MF broadcast arrays routinely do their phasing inside  
the tx shack,
using a lumped-constant phasing and power splitting network.

No reason hams couldn't do something similar, and just coil up the  
phasing lines
in a box.   Switching could then be done with simple manual coax  
switches.
