Big New Radio Telescope Array Listens in on Space
The world's most powerful radio telescope is so sensitive that it can detect a small CB rig operating on a distant planet. The Very Large Array (VLA) Radio Telescope Facility...

Probing Concrete with Radio Waves
Electromagnetic probing can be used to assess the integrity of concrete cofferdam seals. Data are taken using high-frequency transmitter and receiver antennas installed in separate boreholes...

Energy From Space
Patented by Peter Glaser in 1973 the solar power satellite is a concept still mindboggling to some. It is a satellite orbiting 22,300 miles (35,800 km) above earth in geosynchronous orbit....

Computer Design of Antenna Reflectors
Performance of a paraboloidal antenna reflectors is adversely influenced by surface distortions from a perfect paraboloid, which causes path length variations of the RF energy beam. The...

Performance of Foundation for Altair Radar
The foundation for the ALTAIR antenna is a ring beam with a diameter of 118 ft, founded upon coral sand. Loads are applied to the foundation at four points; these points move around the...

Computation of Cutting Lengths of Guys
A method is presented for computing the cutting lengths of cable segments used as guys for antennas and transmission towers. The analysis takes into account both concentrated and distributed...

World's Largest Log-Periodic Antenna
Detailed descriptions of the structural system, design criteria, fabrication of the antenna elements, fiberglass road assemblies, asbestos-cement pressure pipe towers and epoxy joints...

Minimum Weight Design of Enclosed Antennas
The minimization of the total weight of the tiltable component of an enclosed antenna structure with a given topology and a given initial design subject to relative deformation constraints...

Unique Solution for Difficult Rigging Problem
The antenna network of aluminum conductors consists of a series of concentric triangles. The erection was accomplished without ground contact of the conductors. The solution consisted...

Design and Response of the Supporting Structure for a Large Tracking and Receiving Antenna

Discussion of " Structural Analysis of the Haystack Antenna by William R. Fanning"

Closure to "Structural Analysis of the Haystack Antenna by William R. Fanning"

Computer Design of a Tower and Cable System
Three computer programs were developed and used in the design of a large very-low-frequency (VLF) antenna system consisting of a network of cables supported on the tops of an array of...
