Professional Installation Required The Model CA2458 Converter/Amplifier, WLAN radio card, antenna, cables and accessories must be installed as a system by experienced antenna installation professionals who are familiar with Radio Frequency (RF) issues such as gains and losses, as well as local building and safety codes. Failure to do so will void the product warranty and may expose the end user to excessive RF hazard.
LIMITED WARRANTY Young Design, Inc. (YDI) warrants that your device is free of defects in material and workmanship for a period of one year after initial purchase. YDI will, in this period, repair or replace any YDI product returned to the factory, freight prepaid. The YDI warranty covers repairs or replacement (at YDI’s option) of the product only. YDI is not responsible for the cost of removal, reinstallation or shipping to the place of repair.
Installation and Operation Manual CA2458 Converter/Amplifier System 1.0 Description The CA2458 Converter/Amplifier system is a bi-directional wireless data link operating in the 5.8 GHz band. It makes use of existing 802.11b wireless technology up-converted to the 5.8 GHz unlicensed band. The system consists of an 802.11b wireless LAN card, a 5.8 GHz frequency block converter (the outdoor unit or ODU), antennas and accessories.

Senses RF carrier from transmitter and automatically switches from receive to transmit mode. Connectors: Indicators: Lightning Protection: N-female TX and RX LEDs on both the Converter and the DC power injector Direct DC ground at antenna connector.
Mechanical, Power and Environmental Operating Temperature: Dimensions: -20 deg C to +60 deg C Converter/Amplifier: 6.95” x 3.14” x 2.24 ” DC Power injector: 5.4” X 2.4” X 1.3 ” Power: 100 to 240 VAC when using the power supply provided - or 13.8 to 15 VDC @ 1.3 Amp peak. Note: DC power supply must be rated at least 2 amps. Outdoor Mounting Bracket: Kit Weight: 4.0 Accommodates pole/mast diameters from 3/4” to 3” Approx. 3.5 lb.
IMPORTANT: If you or your installer are not familiar with determining power levels within the transmission system, YDI engineers will assist you in planning your system including selecting the cable and antenna required. 6.0 Radio Frequency Safety It is the responsibility of the installer and the owner of the equipment to ensure that the installation complies with government standards for Radio Frequency (RF) and Electromagnetic Field exposure.
8.0 Outdoor Unit Mounting The Converter can be mast mounted using the steel U-bolt included with the unit. Refer to Section 12.0 of this manual, Installation Detail - Typical Installation, for a cabling diagram. The Converter must be installed with the N-type connectors facing downward. Use an open-end wrench to tighten the bolts with the nuts included in the kit. Be careful not to over-tighten the bolts. It is imperative to waterproof the RF connectors on the Converter.
10.0 Typical ODU Installation The picture to the left shows the Converter in a typical installation with a 2-foot dish antenna. The Converter should connect to the antenna with the shortest possible cable. The location on the mast where it is mounted is not important, provided that the connectors face downward. (Note that when this picture was taken, the connectors were not yet weather proofed nor was the cable secured to the mast.).

13.0 Converter Indicators and Connectors CAUTION: Only use high quality N-type connectors. Do not use PL259 “CB” type UHF connectors. Doing so will ruin the N-Female jacks and void your warranty. Transmit LED: This LED glows RED when the Converter has switched to the transmit mode. This occurs when the Converter detects RF power at the N-type connector labeled “To DC Injector”. Receive LED: This LED glows GREEN in the receive mode when DC power is applied to the Converter/Amplifier.
.0 DC Power Injector Indicators and Connectors Red Transmit LED: This LED glows RED when the Converter goes into transmit mode. The Remote Transmit LED is controlled by unique circuitry, which actually detects changes in the DC current traveling through the transmission line to the amplifier. When you see this LED flash, you will know that the remotely mounted Converter is going into transmit mode.
17.0 Operation The system operates automatically and requires no user adjustments. It translates 2.4 GHz signals by 3.328 GHz to and from the 5.7- 5.8 GHz band. For example, a 2.462 GHz signal will go out over the air at 5.790 GHz (See Conversion Table below). Conversion Table 802.11 Channel 1 2 3 4 5 6 7 8 9 10 11 12 13 2.4 GHz Freq.

APPENDIX C Calculating Transmit Power The following information explains how to calculate the input and output power to and from the Converter: 1. 2. Using Appendix A, Table A, convert the output power of the radio device from milliWatts to dBm. The Model CA2458 Converter ODU is optimized to work with input powers between +3 dBm and +8 dBm. Calculate the cable attenuation at 2.4 GHz as follows: Determine the attenuation for the length of your cable at 2.4 GHz.
