What reading level is Wireless Telegraphy And Wireless Telephony An Elementary Treatise book?
To quickly assess the difficulty of the text, read a short excerpt:
At each explosion the power of the machine is relatively very great; but between shots the power falls to nil; so that the average for one second, the power of the machine, or its mean rate of throwing energy off, is comparatively low.
In practice, single-wire antennas are seldom used, and multiple- wire antennas are customary. The purpose of employing a plurality of conduc- tors is two-fold. In the first place, the larger surface of the antenna gives more electric flux in the air when charged,... and this increases the stock of energy held by the antenna prior to re- lease and radiation. In the second place, the larger surface permits of a more free active radia- tion or discharge of electromagnetic waves into WIRELESS TELEGRAPHY ir, Independently of the amount of energy to be released.
Cylindrical Antennas Fig. 27 represents the cylindrical type of verti- cal antenna, one having four parallel vertical t wires and the other sev- enteen. Any convenient number may be used. The wires are usually soldered to two or more metallic hoops H H, which not only strength- en the structure mechan- ically, but also keep the oscillations symmetrical electrically.
