Have a look at my article on feeding a G5RV, in particular Fig 10, the
classic tuned feeder configuration. a 30m long dipole with low loss open
wire line and an efficient balanced tuner is a frequency agile antenna
with good efficiency and good pattern up to 12MHz. Above 12MHz, the
pattern breaks into many lobes and nulls.
As a matter of interest, Mr. Varney, G5RV himself, designed
his antenna for 20m operation because he liked that multi-
lobed pattern. In AZ, I had each of the four major lobes
pointing toward one of the world's large land masses.
