DESCRIPTIONDESCRIPTION
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.
