6. ign concept for the mobile whip antenna which emphasizes to go along well with recent aerodynamic car design 2 Since the antenna employs radialless structure on both 2m and 70cm bands it works well at virtually any place on your car body It can be located on trunk lid roof gutter or any place without effecting vswr characteristics 3 High performance C Load structure is used on both 2m and 70cm bands 4 Both bands can be transmitted or received simultaneously or one band can be transmitted while receiving another band or vice versa simultaneously by using a duplexer 5 24K gold plated center conducter is used in connector section of the antenna 6 Omnidirectionally tltable whip structure enables the antenna to be tilted for any direction by pulling the whip element section lightly And it eliminates troublesome antenna detouchment when your car is parked in the garage Assembly The antenna is packeged in only the top element No 1 element being detached To assmble the antenna put the top element into the top end of upper phase inductor and secure it with hexagonal wrench attached Adjustment THE SUPER GAINER series antennas are all factory adjusted and do not require any adjustment lf center frequency of the antenna has to be altered loosen two set screws at the top of tltable whip section and put the element in and out to have best vswr at desired center frequency Be sure to fasten the screws after the adjustmen
7. t Note 1 The SG7900 employs DC ground structure whip element and ground section outer shell of the impedance matching section are short circuited and center conductor of the feedpoint connecter and whip element are isolated 2 Since those set screws being used throughout the antenna may be loosened due to the Vibration during driving they have to be refastened from time to time after several drives especially the antenna is right off from the Dackage 3 Do not dirve the car with the antenna ttled sicne whip element moves freely when the antenna is tlted 4 Be careful not to be bit your finger into the tltable whip section when the antenna is being erected Specifications Gain Max power rating Impedance VSWR Length Weight Connector Type 5 0dB 2m 7 6dB 70cm 150W Sum of both bands if operated simultaneousIy 50ohms Less than 1 5 1 1 58m 62 29 600g 1 32Ibs UHF male 7 8 wave double C Load radialless gain whip antenna 2m 578 wave three element C Load radialless gain whip antenna 70cm Part name number 17701 No 1 element 17702 No 1 Phase inductor 17703 No 2 element 17704 Phase capacitor 17705 No 3 element 17706 17707 No 2 Phase inductor No 4 element B 05 Set screw B 03 Hexagonal wrench 17708 Omnidirectionally titable whip section 17709 Impedance matching section 2008 1 2 8R105 26d
