I have always used the CFA as a mobile antenna!
Get with the program people, you will be hard pressed to find a better

As a shack antenna, it sucks!
However, what other antenna can you chuck a motor into, slap a
steering wheel and horn on and drive?
You guys are all wet, as usual... <satisfied-smirk>
