Get teh bets and largest aerial you can firt.

The number of elements make a difference though from what I can make
out... the mid-range one has 18 and the top of the range has 43 - i`m not
sure about physical dimensions though

In theory, more elements increases the gain on-axis and reduces
it off-axis, so it should be better if you can accurately perform
the more critical alignment it requires.

However, I'm sceptical that many aerials are really designed that
accurately, at least as far as the physics goes. I suspect much of
the design is to 'look' higher quality so they can charge more;-)
