Practically speaking, there's not a whole lot of difference between 
these two antennas. They are both trapped tribanders with similar 
boom lengths 19 and 18.5 feet, respectively.

I would favor the A4S myself. A couple of reasons. First, I happen to 
like Cushcraft antennas. The A4S has been installed by a large number 
of hams, and it is a proven performer. While perhaps not as efficient 
as some of the modern computer-optimized designs, it will hold its own.

The TH5-Mk2 isn't quite as popular. The Hy-gain probably has slightly 
better mechanical construction, but is heavier. The extra driven 
element probably doesn't buy much in the way of performance, but 
contributes to extra weight and wind load.

I tend to like the lightweight element design of the Cushcraft. It 
might not be so appropriate if you live in an area that gets frequent 
icing. (Although my A3S survived an ice storm with about 1/2" of ice 
on top of the elements)

It would be the A4S for me, choosing between these two. If you are 
trying to pick the best tribander with a 19-foot boom, the Force-12 
C19 series would probably outshine most.
