1. Introduction
The ISA.01 is an Omni-directional wide-band low profile 400MHz to 470MHz antenna for internal or
external applications adhesive mounted on glass.
Its applications are in the automotive industry and telematics. At only 10.5mm thick and 42mm in width,
its semi-flexible properties and strong 3M automotive approved double-sided adhesive allows for
convenient glass installation. ISA.01 antenna offers exceptionally stable peak gain and efficiency across a
very wide bandwidth, tuned to operate optimally on glass, which makes it a unique low frequency solution
in low profile form. Unlike our competitors, Taoglas shows full performance data for our antennas. The
ISA.01 shows real gain figures and radiation patterns INCLUDING cable losses, tested in state of the art
low frequency anechoic chambers. We have invested heavily in research to create a uniquely wide-band
UHF antenna with minimum 70MHz bandwidth that can replace expensive externally mounted antenna
solutions. The wide-band compared to other narrow-band 20MHz antennas delivers more stable
performance in a range of diverse on-glass environments with more resistance to detuning. All low
frequency UHF antennas need to be tuned to suit their mounting conditions. For this reason this antenna
is tuned to be mounted on glass. (i.e. excluding plastic or metal mounting), so is ideal for vehicles or
building windows.
The standard cable is the RG174.
Cable length and connector type are fully customizable
The antenna can be customized for other low frequency bands for a minimum order quantity. Please
contact your local sales office. For mounting applications on plastic please use ISA.06. For mounting
directly on metal please use our FW series whip antennas.
