The RFI range of UHF dipole arrays provide expanded bandwidth, high power ratings and unequalled performance in gain, pattern and intermodulation performance.
Ever increasing costs and site density requirements are reducing availability of antenna positions on prime sites. In order to reduce the overall number of antennas the RFI dipole array series provides system engineers and site owners with a flexible solution to reduce antenna numbers.
EX4040-67 Features:
The Combination Collinear and Dipole Array Similar in many regards to the above arrays this type of combination array employs a collinear antenna as the upper section of the array. These arrays are ideal where tower wind loading is a critical consideration. The collinear antenna fits into a lower section array, which can be essentially any style of our higher gain UHF dipole arrays.
The collinear antenna (COL8 or COL17) is held in an adaptor which can be fitted to any appropriately configured UHF dipole array.
A sample of the more common configurations are provided in the following table. The electrical specifications are very similar to those provided for the individual arrays previously listed within the catalogue.
These lower sections are for use with COL series collinears. They are provided with a through harness to connect your choice of COL8 (UHF), COL15 (VHF) or COL17 (VHF) collinears.
