[Milsurplus] Re: Ongoing hf command antenna

[Dan Arney]

Eric,
  Depending on the type and numbers of HF rigs on board, a probe type. a 
flay isolated flat plate area, an engine nacelle (Jetstar), a wingtip, 
part of the vertical fin and lately a conformal low drag plate area.
Lot of different antennas with automatic couplers with 10 second load 
times. 40 to 1 KW SSB and ACARS data and SELCAL. The ground station 
rings your door bell to wake you up
AB GH has a selective tone and you answer Tango Lima 351  etc.
Most all of the carriers now use SATCOM.
