When I lived in Florida on 1/2 acre, Louis, I started out with a 50' tall
Marconi (flat-top was an 80 meter dipole) using 4 elevated radials and
100 watts. It didn't work all that well. Later, I added about 20 x 100'
radials mostly in about a 180 degree sector favoring Europe. Those
extra radials seemed to make a huge improvement (worked all continents
and about 50 countries before moving away a few months later). I felt
louder at my Florida QTH than I do now from my present city lot
location in California even though I have 10dB more transmit power
(1KW vs 100W).

I say give it a try.
