successful communications between two points is predicted on 50% of the days of in a month. The LUF is the frequency below which successful communications are lost due to ionospheric loses. The OWF, which is somewhere between the LUF and around 80% of the MUF, is the range of frequencies which can be used for reliable communication. -

40 Meter Off-Center Fed Dipole 40 through 20 meters are the most useful bands for portable QRP operation. These bands will enable the portable operator to have both daytime and nighttime capability for short (using NVIS), medium, and long-range communication. Also, the antenna itself is a manageable size for portable operations – even more so with the CHA Pocket OCFD!
