Are you sure you did the installation of that 30 meter coil right?  I have
had 3
of those verticals with excellent results on 30m.  Directional antennas
would be the
answere for 30 meters but I would certainly look at that again.  I have had
ground mounted and worked over 120 countries on 30m with 100 watts and also
had them
mounted up on a 50' tower with an anti radial kit which also worked good.
And no 
difference was made on either 40 or 80 meters as well. Good luck and

to construct a sloper type of antenna for 30M, with the sloper running
