SRL-470

Sinclair has addressed the growing need for specialized antennas in the 900-960 MHz frequency band. The SRL-470 series of panel antennas was designed to meet the needs of the micro-cell market. These compact radome-enclosed, horizontally-polarized antennas provide controlled directional coverage and are suitable for either pipe or wall mounting.

SRL-4702

Sinclair's SRL-4702 features the inconspicuous profile of the panel antennas. This rugged antenna is fabricated with an ABS radome which protects it from the elements. It offers an excellent front-to-back ratio which provides isolation from adjacent systems.
Various degrees of electrical downtilt can be provided to suite virtually any application. The beamwidth of this antenna can be adjusted at the factory to meet your specific needs. A 1Kw power option is available on special order.

SRL-475

Sinclair's SRL-475 is an enclosed dipole array which delivers superior performance in the 824-894 MHz band. This highly versatile antenna is well suited to architecturally controlled applications where a specific coverage pattern and highly dependable performance is required. The SRL-475 has a field adjustable pattern offering horizontal beamwidths between 49 and 130 degrees. Features of this antenna are a low profile, pattern control and a high front-to-back ratio. SRL-470

The unique design, combined with an innovative manufacturing technique, ensures that the intermod levels remain low. The binary feed harness, reflectors and other internal components are isolated yet rigidly mounted and sealed within a durable ABS radome ensuring excellent protection from the elements. In addition, the SRL-475 is manufactured without the use of rivets, metallic screws and non-compatible metal contacts thus reducing the problems associated with intermod. These antennas also feature a special type 'N' female termination which is easily waterproofed and maintained. Sinclair's commitment to providing reliable and versatile components is evident in this series. The distinctive construction of these antennas will provide exceptional intermod protection. To obtain more details about the versatility of these antennas or pattern information, contact your Sinclair representative. Antenna patterns are also available from Sinclair's own computer Bulletin Board System.
