USER MANUAL CG ANTENNA CO LTD CG Antenna CG 5000 AUTOMATIC ANTENNA TUNER USER MANUAL 1 http www cgantenna com USER MANUAL CG ANTENNA CO LTD INTRODUCTION CG 5000 automatic antenna tuner ATU can cover whole HF bands from 1 8 to 30 MHz The CG 5000 is the high power version of the state of art CG 3000 It uses new microprocessor and more big non volatile memory The CG 5000 is independent to any exciters It detects RF frequency VSWR and other information from RF signal So it can work with any exciters without the special data connection The multi signal processing circuit switches the inductance and capacitance to make perfect matching between your radio and antenna system Fast tuning less than 6 seconds for first initialize matching 800 memory channels store the minimum SWR value to make further tuning The solid waterproof case works on the most extreme environments The mounting kit is built by stainless metal to ensure no rust The CG 5000 is designed with Pi matching network It provides more wide tuning range and covers whole HF band Using 8 solid inductors the total inductance ranges from 0 to 32 uH They can give 128 combinations with a resolution of 0 25 uH 5 capacitors are used at the input side the total capacitance ranges from 0 to 6400 pF with 64 combinations Other 5 capacitors are used at the output side the total capacitance ranges from 0 to 400 pF with 32 combinations So totally they give m
3. desired frequency and switch the transmit mode to AM PACKET or any other continuous mode First try low power to tune E g 20 watts Press PTT key CG 5000 will automatically tune You will hear some click click noisy it means CG 5000 is tuning Once the tuner gets the lowest VSWR then tuning will finish and tuner will store all the parameters to memory Also you can check the tuning status from the optional control unit If the green Tuned light is on it means tuning finish XKR WARNING Tuning with high power will damage the tuner Please respect the maximal output power limit Otherwise the tuner will be damaged When you go back to the frequency which is tuned before CG 5000 will pickup the existing L C combination from memory setting and match the system To reset the tuner just simply disconnect the power or use optional control Antenna _ 4 http Avww cgantenna com USER MANUAL CG ANTENNA CO LTD Ground system The CG 5000 must be connected to a good electrical ground Good ground prevents shocks interference and others Use heaviest gauge wire or metal strap available to connect to as large as possible metal object Install a quarter wave length of working frequency wire as counterpoise Attention 1 Check the supply power to tune If the power voltage is too low CG 5000 will not work
