VHF signals from a mobile station using a vertical whip antenna will normally be best received using a:
vertical ground-plane antenna
random length of wire
horizontal ground-plane antenna
horizontal dipole antenna
B-006-07-09:
A dipole antenna will emit a vertically polarized wave if it is:
mounted vertically
fed with the correct type of RF
too near to the ground
parallel with the ground
B-006-07-10:
If an electromagnetic wave leaves an antenna vertically polarized, it will arrive at the receiving antenna, by ground wave:
vertically polarized
polarized at right angles to original
horizontally polarized
polarized in any plane
