The present disclosure relates to the field of television receiving antennas, and discloses an outdoor antenna, comprising a main body and a pair of reflective nets, wherein the reflective net comprises an assembly body, the main body comprises a fixing base, the assembly body and the fixing base are plugged into each other, and the assembly body and the fixing base are connected by a snap-connection, which allows the assembly body and the fixing base to be tightly combined with each other after being plugged in. The reflective nets can be detached from the main body, so that the entire outdoor antenna can be disassembled, which avoids packaging of the entire outdoor antenna and reduces the packaging volume. Furthermore, through the snap-connection, the assembly body and the fixing seat will not be loosened after being plugged in, and can be tightly combined with each other.

A dual-polarized radiating element for a base station antenna includes a first dipole that extends along a first axis, the first dipole including a first dipole arm and a second dipole arm and a second dipole that extends along a second axis, the second dipole including a third dipole arm and a fourth dipole arm and the second axis being generally perpendicular to the first axis, where each of the first through fourth dipole arms has first and second spaced-apart conductive segments that together form a generally oval shape.

A dual band antenna that allows the independent optimization of each frequency band by adjusting the sizes of the antenna elements. For example, an antenna may have two different drivers, one for the high-frequency and one for the low frequency. By using elements orthogonally connected to the low frequency driver, the low frequency driver can function as both a reflector to the high frequency drivers and the low frequency driver without affecting the antenna's performance in the high frequency. The antenna may also have parasitic elements. For example, parasitic directors parallel to the high frequency band driver can be configured to improve performance in the high frequency band. Pairs of additional parasitic directors can be orthogonally connected these directors. These pairs can be adjusted in size to improve performance in the low frequency band with minimal impact on performance in the high frequency band.
