Therefore, there is no need for extra protection for added connectors.
- According to another advantage of the above-described embodiments, the packaging of the radome is simplified (see
figure 4 ) as there is no connector or covering blister which extend beyond the outer shape of the radome. - According to another advantage of the above-described embodiments, the external shape of the radome is unchanged, while supporting a plurality of antenna connectors.

Advantageously, this allows quick cable to connector attachment and detachment, properly tightening of cables to connects, and easy physical access to connectors.
- According to another advantage of the above-described embodiments, the radome may enclose an antennas structure involving a plurality of connectors. For instance, an "antenna" structure may include 12 antenna arrays (6 ports +45° and 6 ports -45°) within different frequency bands.
