JDA maintains an extensive range of specialised test equipment and a field survey vehicle in order to undertake necessary field measurements and coverage audits. JDA's services in this area can determine whether or not a system meets licensed specifications and is operating as designed. We can also undertake interference audits to determine the origin of interfering signals or to find out whether or not a client's transmissions are interfering with another broadcaster.

Some examples of coverage surveys and audits JDA has completed are:

  • Sky Tower's FM transmission system
  • Most of TV3 and C4's network
  • Ruru's FM transmission system

For more information, please contact JDA.
