I have a 1/4 wave inverted L. Prior to this season I fed it through a 2.25:1 
UNUN. This summer I took out the UNUN and made a simple shunt coil of about 3 
uH from bare copper wire, air wound. Put it in a plastic box at the base of the 
antenna and moved a wire tap around until I got the best match. Brought it in 
the house and soldered the tap in place. The match is MUCH better than what I 
got with the UNUN.
