Its a mystery to me why hams would go for a broadband antenna of any 
kind, when a dipole fed with ladder line and used with a decent tuner 
(auto or manual) is cheaper and more efficient. Yet, I constantly see 
hams putting up T2FD resistive-loaded folded dipoles on emergency 
operations centers. There is no deception here: the specs of these 
antennas are published but not many hams read them and realize that such 
  antennas are only about 12% efficient on 80 meters. Now the military 
with frequency-hopping radios needs a broadband antenna because tuners 
can't hop very fast and they add bulk to the portable kit. We change 
bands, but its hardly a freq-hopping mode of operation.

Years ago, I found myself in a city "somewhere in the Middle East". 
There were many embassies within walking distance. I amused myself by 
looking at the the HF antennas on the embassy rooftops. There were a 
couple that used big log periodics, but the majority used simple dipoles 
fed with 600 ohm ladder line- a design that goes back to the 30's and 
40's. Why argue with success?
