1. In this diagram the item U corresponds to the:
a) boom
b) reflector
c) driven element
d) director
====================================
2. In this diagram the item V corresponds to the:
a) boom
b) reflector
c) driven element
d) director
====================================
3. In this diagram the item X corresponds to the:
a) boom
b) reflector
c) director
d) driven element
====================================
4. The antenna in this diagram has two equal lengths of wire shown as ‘X’ forming a dipole between insulators. The optimum operating frequency will be when the:
a) length X+X equals the signal wavelength
b) dimensions are changed with one leg doubled in length
c) length X+X is a little shorter than one-half of the signal wavelength
d) antenna has one end grounded
====================================
5. The antenna in this diagram can be made to operate on several bands if the following item is installed at the points shown at ‘X’ in each wire:
a) a capacitor
b) an inductor
c) a fuse
d) a parallel-tuned trap
====================================
6. The physical length of the antenna shown in this diagram can be shortened and the electrical length maintained, if one of the following items is added at the points shown at ‘X’ in each wire:
a) an inductor
b) a capacitor
c) an insulator
d) a resistor
====================================
