Station engineers can use XField when re?locating FM translator stations to frequencies that are second or third adjacent to full service stations or otherwise protected translator stations. To consider the vertical elevation field of a given antenna the XField program must calculate the ERP of the translator antenna along the ground or at a user-selected height at various azimuths and distances from the translator antenna. XField employs the translator's vertical elevation field and azimuth pattern to produce a graph or table of the points where the 40dB limit is exceeded. A translatorstation can then be brought into compliance by either reducing its ERP, using an antenna with more bays (keeping the higher signal strength away from theimmediate tower location) or increasing the translator's antenna height. XField also includes an IBOC interference calculator, which will calculate the self?interference caused to a hybrid IBOC station when its antenna is not the antenna used by the hosting station.
