Antenna Configuration Test

Nice antenna comparison video here.... only thing that seemed odd to me is that at about the 2:40 mark he mentioned he was testing an Inverted Vee and the feed point was 3 feet off the ground and the peak of the Vee was about 25'. I have never heard of this arrangement. That doesn't mean it isn't done, I just never thought about that. Your thoughts?

I am thinking about doing a test between my attic antenna and my outside antenna on WSPR. My thought is if I can't hear them..... what does it matter if they hear me?
