I would just like to thank all who have replied both on and off the reflector.
The discussion has resolved a problem I have had for many years, so I
am very grateful for that.
I have now done some useful modelling of a top loaded T antenna with
just a shunt coil at the base. The SWR bandwidth looks better on the
model than I have previously obtained with either an L-match or an UNUN.
I also found it interesting to hear the opposing merits of the
lengthened antenna and series capacitor versus the shortened antenna
and shunt coil. I have used both over many years, but my personal
preference is to have the antenna grounded at the feed point.
73, and thanks again for all the help..
