 about Yagis with a log-cell in them.  In the books they look useful animals,
 but I'm puzzled why contesters don't use them, singly or in stacks.  Is this
 mainly to do with the fact that people prefer to buy ready made equipment
 these days, and there aren't any of these being offered presently ??

I found (experimentaly) that using log cell in long boom antennas helps to 
clean up the pattern, widens the bandwidth, improves F/B. Nowadays apparently 
OWA is talking care of all that (?), but I have no hard facts. KLM antennas 
used them, I used them with great succes in Razor (Quad-Yagi) designs.
