EE302 Lesson 13 Antenna Fundamentals.ppt

Conical Antenna A common way to increase bandwidth is to use a version of the dipole antenna known as the conical antenna. The center radiation resistance of a conical antenna is much higher than the 73 Ωusually found when straight-wire or tubing conductors are used. The primary advantage of conical antennas is their tremendous bandwidth.

Modern flat Earth beliefs - Wikipedia

Modern flat Earth belief originated with the English writer Rowbotham (1816–1884). Based on conclusions derived from the Bedford Level experiment, Rowbotham published a pamphlet titled Zetetic Astronomy. He later expanded this into the book Earth Not a Globe, proposing the Earth is a flat disc centred at the North Pole and bounded along its southern …
