Abstract: An antenna assembly comprising a pole and an antenna mounting apparatus. The antenna mounting apparatus is comprised of at least one sleeve which is configured to be mounted on the pole. Advantageously, the sleeve includes three antenna mounting members which extend in a direction parallel to the pole. Flat panel directional antennas are then attached to the antenna mounting members in a manner where the antennas also extend in a direction parallel to the pole to thereby minimize the horizontal profile of the antenna mounting apparatus. The sleeve can be mounted on a support collar positioned on the pole and can be rotated about the support collar to a desired rotational orientation and then secured in the desired rotational orientation. A further embodiment of the present invention incorporates two sleeves, which can be positioned at different positions on the pole, with the at least one antenna mounting member extending therebetween.
