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