I have searched the Towertalk archives and read that log periodic antennas can 
have the undesirable side effect of capturing too much RF; their broadbanded 
capability results in all signals in the antenna's "passband" being presented 
to the receiver. Strong out-of-band signals such as SW broadcast signals, 
strong contest stations, etc. could lead to undesirable performance at the 
receiver -- it is this issue that I am trying to quantify.

I am looking for solid factual experience from folks who have directly 
witnessed how log periodic antennas can affect the front end of today's HF 
transceivers. My ridge-top QTH will have a clear shot to the horizon in almost 
all directions and I am trying to figure out if a log periodic will work for 
me. The other option would be a multiband antenna like the Force 12 5BA or 

thanks in advance,
