Abstract
Disclosed is a low band dipole that has four dipole arms in a cross configuration, and a simplified cloaking structure to substantially prevent interference with radiated RF energy from nearby high band dipoles. Further disclosed is a feed network and dipole stem balun configuration that power divides and combines two distinct RF signals, without the use of a hybrid coupler, so that the four dipole arms collectively radiate the two RF signals respectively at a +45 degree and −45 degree polarization orientation relative to the orientation of the dipole arms.
