I have a small
collection of information about old military HF antennas used
over the World. Presently, three old military automobile HF antennas
are described at the article. The antennas are written 'as it
is,' i.e., I give all information, that
I have had. I know, the information is not complete at all, but,
nevertheless, the information is interesting and it can help somebody
to make own 'car antennas.'
Tuned dipole exhibited in Figure 1 was used in army of the
USSR. Scheme for the antenna is shown in Figure 1a. Tuned dipole made from a strong tube
that has diameter 15 to 30 mm. The tube is installed at height
of 1-1,5 m above the roof of an automobile and goes out approximately
on 1 meter for overall
dimensions of the automobile, as it is exhibited in Figure 1b.
Tuned dipole has high radiation both at low and high (mostly)
angles. It allows the antenna to make links by earth and reflected
from ionosphere wave.
