One of JDA's core areas of expertise is television broadcasting; we have a great deal of experience in this area, right through from initial planning to network design and installation.
JDA played a central role in the creation of New Zealand's first private television network, TV3, by providing them with the transmission testimony for the tribunal hearings, enabling them to win the first warrant for private television in New Zealand. We were also major contributors to the ground-breaking development of the VHF channel plan which was implemented for the three networks: TV One, TV2 and TV3.

JDA also discovered that it was possible to fit a fourth television network, TV4, into the VHF channel plan and, after providing appropriate interference analysis, managed to convince the Ministry that the new plan was feasible. As a result, TV4 was created with minimal acquisition of new spectrum.
JDA has had custom software created to predict coverage from arbitrary transmission sites using a digital terrain database and sophisticated diffraction algorithms. We have used this software extensively for TV3/TV4 to select appropriate locations to achieve the best coverage possible with the minimum number of sites.
We have also been used by TVNZ in several special projects. Our independence allows us to offer complete, confidential services to any client.
