Uhf version of the IsoPole´s, offers the same features
and performance of the Vhf antennas, as:
degree radiation angle, so the major lobe is oriented
on the horizon giving the maximum gain on the length.
Decoupling sleeves offer greater efficiency than the common
radials, producing a uniform omni directional pattern
and a great mechanical strength.
frequency coverage than other collinear antenna.
can be tuned for commercial, military or amateur applications
without re-tuning across the entire band with less than
2:1 of SWR with no compromise for the transceiver.
Constructed with the best quality materials available
of high resistance corrosion aluminium alloys, stainless
steel mounting hardware, and insulation resistant to
UV mainly manufactured for satellite applications; the
connector is inside the mast fully weather protected,
offering a linear and constant performance.
It is an ideal choice for repeaters and trunking systems,
and can replace arrays of 4 dipoles in omni directional
configuration with similar performance and saving costs
of installation, less wind load area and high power
handling if required.
has a high noise threshold, capable of discriminating
weak signals of spurious or static noises, and it is
also DC grounded.
The installation of the SPECTRAL IsoPole is very simple,
it requires only a metallic tube (not supplied with
the antenna for a reason of length) of 32mm (1-1/4in)
and 0.70meter (28 in) for mounting , the antennas
are supplied with their own masts and it is only necessary
to spend a few minutes assembling and tuning by a
simple length adjusting according to the chart.
