HFGCS equipment?

[N4RMT]

Just curious, have been for years. What actual equipment does the HFGCS use? Does anyone know anything about the transmitters, antennas or amplifiers used? I'm sure it's not some dude on an FT-1000 with a G5RV. Always been intrigued by that type of stuff.

I'm pretty sure this is one of the antennas in common use:

AS-3482/GRC Horizontal Log Periodic RLPA Antenna NSN 5985-01-093-2125

Note the 3 1/8" EIA feedline.

No clue on the transmitters or amps though.

There's one of those on the roof of the pentagon. Saw it this weekend.

Google for Elkhorn Communications Detachment and use the streetview to see what an actual HFGCS farm looks like. The insides of the comms center is kinda sparse, the radios are in racks in another room, the ops sit in front of lcds displaying the control program complete with freq lists. I've heard (cough) that some ops would tune to the cb band and send a few eams and skykings on occasion. So that'd be 10kw to a 3/30 lp with gain.

A few years old but interesting nonetheless:

as long as they end it with RADIOOOOOOOOOOOOOOOOOOOOOOOOOOOOOO they'll fit right in with the rest of 11m.
