Kraus gives the W8JK close-spaced beam (spacing:1/8-wavelength) a gain
of 5.8 dBi on page 552 in his 2002 3rd edition of "Antennas". A dipole
in free-space has a gain of 2.14 dB over an isotropic, so the W8JK has a
gain of 3.66 dBd. This makes the W8JLK comparable in gain to other
2-element beams in Arnold B. Bailey`s "TV and Other Receiving Antennas"
catalog.
