you're right.
But only from the outside of an antenna you can't deduce how much metal it contains, to transmit. There are several cases, where the manufacturers build huge plastic-antennas containing a little 1cm long cable. In comparison the ouput-power of a outwards smaller-looking antenna was higher.
That means to me, that visual comparisons are useless (unless we'll slice it - but who wants to do this?).
