A first-hand look at the extraordinary collapse of FTX, Alameda Research, and Sam Bankman-Fried In SBF: How the FTX Bankruptcy Unwound Crypto’s Very Bad Good Guy, accomplished crypto reporter Brady Dale presents an engrossing take on the spectacular and sudden implosion of FTX, Alameda Research, and their associated companies, as well as the criminal indictments of Sam Bankman-Fried and several of his associates. In the book, you’ll go beyond the salacious details and tawdry gossip to grasp the real lessons to be learned from one of the most dramatic corporate failures in living memory. The author explores: The often-confusing world of cryptocurrency and decentralized finance, offering a deep understanding of both industries The history of Sam Bankman-Fried, what smart money players had to say about him in 2019 and 2020, and why many decentralized finance professionals considered him a “pirate” even before FTX and Alameda blew up What the aggressive lobbying campaigns waged by FTX and Sam Bankman-Fried reveal about the latter’s motives and goals An extraordinary account of almost unimaginable wealth, greed, and hubris, SBF is a can’t-miss account of a fascinating corporate tragedy that continues to unfold to this very day.

Eight short backfire (SBF) elements aligned on a common planar reflector form a highly efficient fan-beam array capable of yielding a maximum gain of approximately 24 dB. The influence of parameter variations on the array patterns and directivity was experimentally determined by varying the frequency. Normalized design parameters for highest efficiency and for circular polarization capability are tabulated. All array dimensions are given in wavelengths so that each application can easily be scaled for any desired frequency.

Four-element short-backfire (SBF) arrays have been shown to yield maximum gains of approximately 20 dB. The influence of parameter variations on the array patterns has been experimentally determined. Specific parameter values required to yield certain pattern characteristics--for example, highest gain, lowest sidelobe level, equal half-power beamwidth, or equal beam shapes in both the E and H planes--have been established. Tables of the normalized design parameters are given for construction purposes. All array dimensions are indicated in wavelengths so that each model can easily be scaled for any desired frequency range. (Author).

Sixteen-element short-backfire arrays have been shown to yield maximum gains of approximately 25 dB. The influence of parameter variations on the array patterns and directivity has been experimentally determined by varying the frequency. A table of the normalized design parameters for an area efficiency of approximately 90 percent is given for construction purposes. All array dimensions are indicated in wavelengths so that each application can easily be scaled for any desired frequency range.

A four-element short-backfire array was designed, fabricated, and experimentally tested for use as a receiving antenna of low level atmospheric noise at 920 MHz. A complete set of design dimensions is presented as well as the resultant radiation patterns and frequency curves of sidelobe levels, half-power beamwidths, and input impedance. The effects of variations on the size and shape of the main reflector are discussed, especially when efficient operation with low sidelobes or high gain is of prime importance. Supporting data and tables of optimum design dimension are also provided for future VHF or UHF antenna applications in the gain range of 17 to 20 dB.
