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 perfor-
mance. 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 90owithout 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.
