Sirio Antenne TORNADO 27 5/8 Manual

DESCRIPTION

DESCRIPTION
5/8 antenna for base station working on 27 MHz. It is made of anti-corodal aluminium tubes and supplied with
jointing sleeves of polythene to guarantee a perfect waterproofing. Strong and easy to install, it allows very good links.
REMARK Tornado 27 is an antenna that is influenced by the height from
the ground plane where it's installed. Unfortunately it's difficult to give the
correct instructions as the places where antennas could be installed are so
different in sizes and types that's impossible to give the correct way to
mount it. However we suggest to carefully verify the height of your
installation pole in order to avoid too much influence of the ground plane
to the antenna performance. Suggested length of final element for the 27
MHz is L=1120 mm but we recommend to get the fine tuning by checking
with your SWR-meter as the ground plane can highly influence the
performance of your antenna.
