Can't vouch for the quality of the antennas since I just ordered them,
but Don Pansier at Delta Pop Aviation (www.deltapopaviation.com) is
great to deal with and offers a great price on com and transponder,
UAT antennas.  Got his name from BIll Moffitt from NavWorx who said
there performance was the same as the Comant's.
