Imagine that in part E8, you had placed the compass due East of the wire. Draw two vector diagrams of the magnetic field felt by this compass: One with the current OFF and one with the current ON. Each diagram should show the magnetic fields from any relevant sources as well as a vector indiacating the total magnetic field. For this problem, assume that the current flows upwards (in diagram it is out of page).
A dipole antenna dimensions has been designed to operate in 65MHz.
Will the same antenna work properly if frequencies a) 130MHz b) 195MHz are used?
Your answer should include the current distribution and impedance variation along the length of the antenna and how those are affected when frequencies of 130MHz and 195MHz are introduced. Also, include sketches of radiation patterns with respect to the changes in frequencies used.
Make sure you give descriptive answer in order to achieve full marks. Use diagrams to help you with the answer.
