BMT,
Not an Echo but I'd sure like to play in this round! Please consider me for "phone a friend"!

I once was an 05B/18E many years ago. 
I too endured the torture of learning International Morse Code and learned how to make antennas from junk.
How do you think that I was able to try and guess what type of antenna that was?

Looks like an AS-3482. It's some model of rotatable log-periodic antenna. Directional and good for medium to long range HF.

albeham nailed it!!
Used by the Air Force with the Global HF net.
Try 11.175USB and 8.992USB.
8.992 come's in LIMA CHARLIE here in FL using an end fed long wire.

Radiation pattern..... (I would say main lobe orientation, but we often used the back lobe of an LPA for shorter links...)
ability for multiple stations to access....
