Why use an NVIS antenna?

To work the Skip Zone {out to about 1000 miles}.
Areas behind obstructions and in dense foliage.
To hear the near in stations just beyond ground wave range.
Great for Field Day and contesting as a "Gap Filler" antenna.
Easy antenna for HF mountain topping and camping trips to get RF out of deep
canyons.


Limitations
Must work frequencies below the Maximum Usable Frequency (MUF).
This is not a DX antenna.
Needs to use an antenna tuner for good match.
Power Limited to about 200 Watts.
Beverage Mode Losses limit achievable gain.
