Mlongoti wa logarithmic spiral ndi mlongoti wotambasuka, wotambalala wokhala ndi mawonekedwe apawiri polarization komanso kuletsa ma radiation. Nthawi zambiri amagwiritsidwa ntchito m'magawo monga mauthenga a satana, miyeso ya radar ndi kuwonera zakuthambo, ndipo amatha kupeza phindu lalikulu, bandwidth yotakata komanso ma radiation abwino. Ma antennas a Logarithmic spiral amagwira ntchito yofunikira pakugwiritsa ntchito njira zosiyanasiyana zolankhulirana ndi kuyeza, ndipo amagwiritsidwa ntchito kwambiri pamakina olumikizirana opanda zingwe komanso njira zolandirira ma sign m'malo osiyanasiyana ovuta.
