NVIS is can normally only be used on frequencies from around 2 to 10 MHz. Frequencies of 2 – 4 MHz are typical at night and 4 – 8 MHz during the day. CHA MPAS LITE Page 4...
Parts of the Antenna The CHA MPAS LITE antenna is comprised of the following components, see plate (2): Plate 2. CHA MPAS LITE Components. Matching Transformer. The Matching Transformer is a CHA HYBRID MICRO and provides impedance matching for the CHA MPAS LITE antenna.
End Fed Inverted “V” Configuration The CHA MPAS LITE, End Fed Inverted “V” configuration, see figure (1), is a short to medium range HF antenna. It can provide good medium range communication on all HF frequencies and acceptable NVIS propagation below 10 MHz.
