PRACTICE EXERCISES:
30. The best types of wire to use in antenna repair or replacement are
______________ and ______________.
31. When preparing an expedient antenna to replace a vehicle whip antenna,
it is necessary to ______________ the answer to the formula L =
142/F(MHz) by ______________ to compute the correct physical length.
32. WD-1/TT field wire may be used to replace or fabricate antennas.
The
two separate wires will act as a single conductor if they
are
__________ _______________________ at the ends.
33. You, a radio operator, have lost the upper portion of your vehicle
whip antenna.
You decide you can replace the lost portion with an
improvised wire antenna.
The remaining lower section of the antenna
is 0.7 meters long.
You are operating at a frequency of 75.50 MHz.
What is the length of wire needed to fabricate the top portion of your
antenna? (Use space below for computations.)
