Dual band VHF vehicular antenna working on 45...60 MHz and 135...175 MHz by means of the attached cutting diagram. Its bottom coil allows very good impedance adjustment and its conic stainless steel whip is very flexible. All the metallic components are made of chromed brass or stainless steel for the best robustness and it can be supplied with a UHF-male (PL 259) connector suitable for the fitting on magnetic mounts, angular connector or portable RTx.
