Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual can be significant. In some cases, there can also be a risk to human life by not protecting against lightning entering a building through wiring or improper grounding. If you do not have experience in this type of installation practice, it is strongly suggested that a qualified electrician and/or telecoms professional is consulted during the installation of the equipment and wiring. 4.2.

EX-2.4i Installation and Maintenance Manual 40-60 VDC Figure 4-5: ++ DC Connection Once the wires are connected to the mating connector, do not connect to the radio and first test the DC connection to the connector from the DC supply. Engage power on the DC supply, and use a volt meter to verify proper voltage level and polarization. Verify that the RF connector is properly terminated, per section 4.2.1 above.
Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual The following list of antennas is recommended in conjunction with this product. In some countries, antennas exceeding a certain level of gain may be unlawful. Refer to section 2.2 for details on regulatory limits.
Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual 4.3.1 Initial Antenna Mounting The antenna should be the exact model recommended by the path and site planning engineer(s). The antenna should be mounted at the proper height, mast/mounting location and polarization orientation also as determined by the path and site planning engineer(s).
Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual measures can be taken to keep the connector clear. Extra care must be taken if the antenna is installed during inclement weather to be certain that no moisture gets inside the antenna connector at any time. The antenna may be aimed at this point in the general direction required for the link.
Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual connectors. For waveguide, the waveguide flange can typically accommodate a direct adapter to an N connector, or alternatively, the antenna can be purchased with a direct waveguide connection. But often a flexible coaxial jumper is needed to connect between the waveguide to the antenna, as waveguide is generally inflexible and can be mechanically challenging to align to the exact antenna connector location.
Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual Once again, a drip loop may be required, and proper securing hardware and grounding needs to be accommodated. As soon as practical, the connected ends of the transmission line to the antenna and lightning arrestor should be weatherproofed.
Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual needed to allow for ease of connection to the radio’s RF connector. A properly specified 90degree connector can often eliminate this need. Or an installation with space accommodated around the radio for a gentle bend radius of the transmission line can also accommodate a direct connection. In all cases, be certain that the transmission line is not providing any pulling force onto the RF connector of the radio.

Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual In this test, it is highly desirable to RF cables that are pre-tested, known good and known loss at the operating frequency. If the cables are short (in the range of 6 feet or less), you can estimate the loss, including connectors, to be less than 1dB each. The estimate of cable loss is critical to the overall confidence of the measurements made in this test.

Exalt Communications Inc. EX-2.4i Installation and Maintenance Manual Appendix C - DC Coupler for Antenna Alignment C-1 Introduction One challenge associated with an all-indoors radio construction is the alignment of the antennas. It can sometimes be challenging to place the radio near the antenna alignment personnel, and can also be challenging to run a separate set of wires for the voltmeter to be in view of the alignment personnel.
