B-5030-G Instruction ManualR.F.AmplifierWARNING:DO NOT PROCEED WITHOUT READING THIS PAGEThe B-5030-G produces at least 300 watts of VHF R.F.power and is not to be taken lightly.Severe R.W.burns can be sustained at this power level!Power Supply:This unit was designed to operate at 13.8 volts with a power supply that provides60 amperes continuous current.This voltage is measured under full load.The nominal currentdraw of this amplifier is 46 amps,and should be considered the minimum current value.Due topower transistors matching,some amplifiers may draw up to 50 amps and put out up to 350 wattsR.F.power.Therefore,a power supply should be selected that delivers at least 55 to 60 ampsmore than the nominal current value.Amplifier:This unit was designed to operate at I.C.S.-Intermittent Communications Service(50%Duty Cycle,i.e.,5 minutes transmitting,5 minutes receiving).The amplifier duty cycledetermines the dissipation rating Ref.1992 Radio Amateur duty Handbook page 5-9.This unit should not be operated with the cover removed The cover confines R.F.radiation,including harmonics,to the inside of the case.Operation of the unit without the cover couldresult in direct harmonic radiation.The harmonic filters contained in the circuit will notsuppress direct radiation.Glass mount type antennas are not suitable and may explode your window if used with this muchpower.A minimum of type RG-303 Belden HI Temp (200c)coax must be used at the connectionbetween the output connector and antenna (or next stage if B-5030-G is used as a driver)orbreakdown may occur.Further,double shielded coax is recommended in mobile application asR.F.may leak into the electrical system of the mobile application (i.e.computerized typeignition,etc.).The B-5030-G draws a nominal DC current of 46 amps and most alternators are rated at onlyslightly above this value.Check with your owner's manual of the vehicle you plan to install theB-5030-G in to determine if you need a larger alternator.Remember to calculate a worst casescenario;i.e.headlights,heater (defroster or A/C),windshield wipers and radios.Remember thatalternators are rated at highway cruise speeds and not stop-and-go traffic.MIRAGE is not responsible for dead batteries in mobile installations,or damage to anything thatwas caused by poor engineering practices by the consumer of this product!Failure to comply with these instructions may void your warranty!
