DESCRIPTION
VHF vehicular antenna working on 139.3-175 MHz by means of the enclosed cutting diagram.
It is made with the very best materials to guarantee the maximum strength and the best performance. The whip, made of 17/7 PH stainless steel, is very flexible and incorporate a custom
inclination system that allows it to be tilted to 90o without using keys or tools. Also a particular
attention has been paid to the UHF-male antenna connector with a goldplated center pin, a
"Teflon" insulator and a silicone rubber gasket for a perfect waterproofing.
