A Parasitic Lindenblad Antenna for 70cm 3 AMSAT PROCEEDINGS 2006 Abstract A traditional Lindenblad antenna uses four, dipole, driven-elements to create a circularly-polarized, omni-directional radiation pattern.
From August 2007 QST © ARRL L indenblad is the name of a type of antenna that is circularly polarized yet has an omnidirectional radia- tion pattern.

The certificate of incorporation was signed on March 15 by six founding families: Anna and Walter Bastedo, Helen and Harry Bowser, Nancy and Ralph Coker, Elsie and Nils Lindenblad, Mildred and H. Theodore Sorg, and Violet and Thurland Wilkinson.
Lindenblad improved on the idea of a sleeve dipole element, adding a gradual impedance transformation to make it more broad banded. RCA chose Lindenblad's element (seen in cross-section in Figure 6a) for experimental use in television transmission.

In 1940, Lindenblad  filed a patent that described a helix traveling wave amplifier similar to the helix traveling wave tube. In Lindenblad's amplifier, the signal was applied to the beam using a grid in the electron gun.
I continued to research antennas and next tested a Lindenblad , again made with twinlead. It was a little better than the turnstile but both harder to construct (I built it on a square cardboard box.) and even more of an eyesore.
Lindenblad arrays provide circularly polarized omnidirectional coverage from an antenna which is mounted around the supporting member, but again the complexity of the device - with four dipoles and four baluns - makes it very expensive to produce.
