One of my coworkers gave me this link to study, more as "This is how a professional designs a project" then for me to attempt to construct: "A High Performance Active Antenna for the High Frequency Band" at

It is a good reference documents as it covers the majority of the design criteria for such an antenna.
Interesting the performance of the final design is pretty close to that of the popular PA0RDT and the slightly better PA3FWM E-Probe antennas, both of which are much simpler circuits.
