Prepare installation
Planning
Calculations for coverage area, metal loss, signal sources, power outlets, dissipating heat
and ventilation for loop driver placement and other practical installation issues, must be
done prior to the on-site installation. Please refer to www.univox.eu/planning
Use Univox Loop Designer (ULD), a free, web-based project planning and design tool that
quickly and accurately assists in the design of loop systems.

Tools required
• Copper tape tools, e.g. crimping tool, double-sided adhesive tape, printed warning tape
• General audio installation tools, e.g. Ohm meter
• Field strength meter, e.g. Univox FSM 2.0
• Listening device, e.g. Univox Listener
Loop cable
Always install a twin core loop cable to secure necessary connection options, especially
vital in environments with uneven metal loss. Univox twin core copper tape gives top
efficiency with low induction loss. Use a junction box to alternate between single, double
and twin turn loop connections.
Use a feed cable (twisted or twin wire) between the junction box and the loop driver, as
well as between the loop figuration and the junction box or loop driver.
