Communication Systems - Engineering

Q1:

The line of sight communication requires the transmit and receive antennas to face each other. If the transmit antenna is vertically polarized, for best reception to the receive antenna should be

A horizontally polarized

B vertically polarized

C at 45° within respect to horizontal polarization

D at 45° with respect to vertical polarization

ANS:A - horizontally polarized

The correct way of reception is that the two antennas (transmit and recevier) must have the same polarization otherwise it will have a fading. So, for your case the receiving antenna must be vertically polarized. Best is to have vertical polarized antenna.
