TracPhone

Each footprint map indicates coverage areas based on EIRP (Effective Isotropic Radiated Power), a value representing the satellite signal strength in those areas. The higher the number, the stronger the signal.

In general, the size of the antenna’s reflector determines the minimum EIRP it will require for TV reception. Since larger antennas can collect more of the satellite signal, they can tolerate weaker power levels and offer a wider operating range. For example, the 32” (81 cm) TracVision TV8 can receive satellite signals down to an EIRP of 43 dBW, while the much smaller 14.5” (37 cm) TracVision TV3 requires a minimum EIRP of 50 dBW for TV reception.

The bottom line: If you’re located within a coverage area that has an EIRP equal to or greater than your antenna’s rating, you should have no problem getting crystal-clear TV reception.

Many other factors besides EIRP affect the ability to watch TV with a given antenna size. Please see your authorized KVH agent for details.
