DESCRIPTION
Dual-band vehicular antenna working on 2m and 70 cm bands. 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.
