Bill,
This won't answer the question but here is some info to research if you
haven't already..
The first link to the W8JI website has performance results for different
types of RX antennas.
The 2nd is an article on short loop antenna
The 3rd is a good source of info on pennants and how to make them.
There is an article in the latest NCJ about phased pennants and their
performance.

Good reading..
