In a antenna lexicon I found something about a cloverleaf antenna from

for BC stations.

I'm not aware of any vertical antennas with cloverleaf patterns
so I am going to assume it is a horizontal antenna (as used for
BC shortwave).

A horizontal dipole longer than 1.25WL tends to have a multi-lobed
radiation pattern, at one point, resembling a cloverleaf. Such a pattern
is pretty much four-lobed when the dipole is about 1.6WL. At shorter
wavelengths than that, it exhibits more than four lobes and at high
multiples of the 1/2WL resonant frequency, becomes essentially an
end-fire antenna.

I Remember back in early 60's a number of hams in my home town built
clover leaf antennas for 2 & 6 meters.. if my memory serves me right
they were horizontally mounted and worked quite well for 2 & 6 Mtr AM
in those days .. I used one as a novice for 2 mtrs. Novices had 2m AM
priviledges back then. But I had nothing to compare it to so can't say
it was better or worse tnan any other 2m antenna. Also if memory serves
me right it was mad up of 3 heart shaped full wave loops condected in
paralell and fed with a single coaxial line.
