DESCRIPTION
VHF radialless vehicular antenna working on 2m band. The very best materials have been used
to guarantee the maximum strength and the best performance. The whip, made of 17/7 PH
stainless steel, has an inclination system that allows the 90
o
tilting without using keys or tools.
Also a particular attention has been paid to the UHF-male connector with a goldplated center
pin, "Teflon" insulator and silicone rubber gasket for a perfect waterproofing.

ADJUSTMENT:
all SIRIO HP Antennas are factory
adjusted and no additional tuning is usually required.
However, if the center frequency needs to be changed,
please follow these simple directions:
1. Release the allan-screws on the whip using the supplied
key
2. Move the whip in or out as needed to obtain a low
SWR at your prefered frequency range.
3. After tuning, re-tighten the allan-screws to lock the
whip.
TILTING:
all SIRIO HP Antennas have
an inclination system that allows the
90
°
tilting without use keys or special
tools.
