Topband: T Vertical feed

Good point, Jim.  Or, go the extra distance and add L too and make it a 
complete low-pass L as was mentioned.  Then, the ATU on the shack table can 
breath a sigh of relief when needed with reasonable band excursions.

Even better for the industrious builder is to remotely motorize L and C. 
It's also possible to play around with T dimensions to minimize X at the 
feedpoint, but for me, that's too much tinkering up in the air :-)
