Yeah Butch, that seems to be the consensus on the Tower Talk listserve. 
It's a relatively good performing antenna but because of its inherently 
off balance design, usually generates large common mode currents and 
that creates unwanted RF into the shack. You can help to mitigate this 
with a properly design multi-core choke and because of the large 
impedeance required by that choke, they will saturate at high power and 
burn up so that antenna is best suited for low power applications.
