1. GAINER 2m 70cm DUAL BAND HIGH PERFORMANCE MOBILE WHIP ANTENNA OMNIDIRECTIONALLY TILTABLE WHIP STRUCTURE CAPABLE OF RECEIVING 300MHZ BAND REPEATER FREQUENCY COMPATIBLE SG7500 OPERATING INSTRUCTIONS Description 1 THE SUPER GAINER series antennas employ our new design concept for the mobile whip antenna which emphasizes to go along well with recent aerodynamic car design 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 High performance C Load structure is used on both 2m and 70cm bands 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 24K gold plated center conducter is used in connector section of the antenna Omnidirectionally tiltable whip structure enables the antenna to be tilted for any direction by pulling the whip element section lightly And it eliminates trou2. 1412570 360 300MHz SG7500
