5. License Exam Questions of the week

One question is drawn from each of the three question pools. Steve, AE8AT,
is providing these questions.  Thanks Steve

Answers are at the end of this email.

We received a question regarding the strange mix of letters and numbers that
begin each question.  Every exam question has a unique combination of
letter-number-letter-number.  The first letter is a T, G, or E to identify
the question pool: Technician, General, or Extra.  Next is a single number
representing the category, for example, category zero is safety in all three
exam pools.  The first letter-number pair is called the "sub-element".   The
second letter is a "group" containing related questions.  Example,
sub-element G8 is Signals and Emissions, with group C of that sub-element
being Digital Emission Modes.  The questions are numbered sequentially:
G8C01, G8C02, and so forth always with a 2-digit number at the end.  The
question identity is included in case of a typo or some "help" from
autocorrect obscures either the question or the answer.  

Field Day is this weekend June 22!  If you are not participating in the
"field" consider hopping on the air to provide contacts.  Or bring your
kids, nephews, and nieces to a Field Day near you using the ARRL locator at

G9B05 How does antenna height affect the horizontal (azimuthal) radiation
pattern of a horizontal dipole HF antenna?

A. If the antenna is too high, the pattern becomes unpredictable

B. Antenna height has no effect on the pattern

C. If the antenna is less than 1/2 wavelength high, the azimuthal pattern is
almost omnidirectional

D. If the antenna is less than 1/2 wavelength high, radiation off the ends
of the wire is eliminated

E9H02 Which is generally true for low band (160 meter and 80 meter)
receiving antennas?

A. Atmospheric noise is so high that gain over a dipole is not important

B. They must be erected at least 1/2 wavelength above the ground to attain
good directivity

C. Low loss coax transmission line is essential for good performance

D. All of these choices are correct
