V-Soft Updates RFHaz

Version 4 of RF hazard software available

V-Soft Communications says that RFHAZ 4 is a serious update of its longstanding RF hazard program.

V-Soft, RFHAZ 4, RF hazard softwareIt considers the FCC’s five new categories for FM EPA antennas and it graphs multiple antennas on a given tower.

RFHAZ 4 also follows the FCC’s current practice of graphically identifying the point of the highest power density at perpendicular distances from the tower. Also, RFHAZ 4 provides for graphical examination of multiple antennas at numerous RF density scales from a minute observation with maximums not exceeding 50 µw/cm² centimeter to a maximum scale level of 3000 µw/cm². The user can choose to display the graph as either “Power Density” or as a “Percent Maximum” of the FCC levels for controlled or uncontrolled areas.

For FM calculations, the user can select one of the five new antenna classifications, then, with the inputs of power and antenna height above ground, RFHAZ 4 uses the EPA studied antenna patterns to show power density. These vertical elevation patterns are included with the data files supplied with the program or the user type in and save a manufacturer’s pattern from disk file. The user can select RF emissions calculations to consider the effect of a mix of array elements and element spacings (in wavelengths).

In addition to graphs, RFHAZ 4 will print a tabulation of both the vertical and horizontal power density levels and, when multiple antennas are used their sums in µw/cm² from the tower to user’s selected distances from the base will be shown. The program considers the impact of antenna arrays having from 1–16 bays as well as those with less than full-wave spacings.

RFHAZ 4 also handles LPTV and DTV duties.
