1. MANUAL M5T5 8 iftron MONDO STINGER 5 8 MS1B 8 27dBm 500mw 5 8GHz A V D Transmitter USER MANUAL Introduction The Mondo Stinger 5 8 is an extremely compact microwave AV transmitter operating in the 5 8GHz frequency ISM band Designed specifically to avoid interference from 2 4GHz radio sources such as WiFi remote controls and other similar emissions the Mondo Stinger 5 8 broadcasts NTSC or PAL SECAM video plus two microphone and line level audio data channels The Mondo Stinger 5 8 featuresa highly efficient on board switching power supply for both the transmitter and our plug in Universal Camera Power Supply UCPS as well as an exclusive battery saver Mondo Stinger 5 8 delivers ultra wide video bandwidth for unrivaled video quality when paired with Iftron Yellow acket Pro 5 8 Diversity or Nano 5 8 Modular ultra wide band video receivers Considerable development has gone into the design of the Mondo Stinger 5 8 Please read this manual thoroughly so that you may better understand the features and operation Caution For proper performance and longevity proper cooling is required See 12 below Caution Never operate without a 5 8GHz rated antenna ordamage will occur Notice This transmitter must be operated in accordance with applicable regulations Features and General Information 1 7 channels from 5 740 to 5 860 GHz 20 MHz channel spacing 2 500mw 27dBm 1dBm of output power 3 Each Stinger 5 8 ships2. ble of picking up a whisper at great distance the amplifier will not overload even if you scream directly into it For line level audio or data input use the lower pads marked line See specifications later in this document for more information Note Your receiver must be capable of receiving this second side channel The Iftron Yellow acket Pro iscompatible Mounting and Cooling Mondo Stinger 5 8 employs an exclusive integral cooling fin and heatsink to aid in removal of excess heat Buildup of excess heat will reduce the performance and life of this transmitter thus we recommend that the transmitter not be wrapped in foam or otherwise insulated Best performance can be achieved when mounted with a bracket using the SMA and included hardware asthe mounting point ina mannerthat allows moving airto reach the transmitter 3 Antenna Placement Placement of the antenna is important for best performance Place the antenna such that no structures block the antenna from the receiving antenna This is especially important if potential obstructions are made of metal or carbon fiber If mounted on an aircraft consider mounting the antenna low on the airframe and pointing down and to the rear by 30 degrees Battery Saver Operation Mondo Stinger 5 8 features an exclusive battery saver that helps prevent overdischarge of lipo batteries The on board 4 slide switch sets the saver to either 2 or 3 lipo celloperation When propery set the t
