Smallest Nanoantennas For High-speed Data Networks Oct 26, 2009
These gold antennas act physically like radio antennas. However, the latter are 10 million times as large, they have a length of about 1 m. Hence, the frequency received by nanoantennas is 1 million times higher than radio frequency, i.e. several 100,000 GHz rather than 100 MHz. (Science Daily)
What's behind wireless lease agreements? Oct 18, 2009
Many towns and cities in the Capital Region have lease agreements with cell-phone companies that allow them to place radio antennas on structures like water towers and keep power equipment below on the ground. As an example, here are the monthly payments the town of Bethlehem collects from cell carriers that rent space on its water tower at 308 Kenwood Ave. The rents typically rise either 3 or 4 percent each year.

Raging Fire Threatens Mount Wilson Sep 3, 2009
"Update, 7:00 a.m. PDT Wednesday, Sept. 2: No change overnight. Officials say "aggressive water and gel drops from aircraft" helped keep back the fire.Update, 5:40 p.m. PDT Tuesday, Sept. 1: The Los Angeles Times : "Firefighters were frantically trying to save the historic astronomical observatory and dozens of critical TV and radio antennas from destruction. By 3 p.m., the fire was approaching closer than ever from two directions: one-half mile to the north and three-quarters of a mile to the... (SkyAndTelescope.com)
Avalanche! The Incredible Data Stream Of Solar Dynamics Observatory Aug 13, 2009
" To gather data from all three instruments, NASA has set up a pair of dedicated radio antennas near Las Cruces, New Mexico. SDO's geosynchronous orbit will keep the observatory in constant view of the two 18-meter dishes around the clock for the duration of the observatory's five-year mission. Not a single bit should be lost. "We're ready," says Pesnell. "Let the avalanche begin. " Adapted from materials provided by . Original article written by Dr. Tony Phillips, NASA Heliophysics News Team.... (Science Daily)
For sale: House and Senate buildings Aug 6, 2009
The Republic was not kind to Wright's plan, calling it an "Arabian nights fantasy adorned with television and radio antennas.". By May 1957, the governor called for another committee to consider Capitol plans. (AZCentral -- Travel)
Apollo 11 40 years later Jul 21, 2009
"For several hours you reporters would have been speculating, guessing about possible problems, and we didnt want one of you inventing stories, Neil grinned. Thats why we put in a four-hour sleep and rest period we hoped we would never use.We laughed, and Neil laughed, and he added, Everything went much faster than we expected.Most of us were having dinner when the call came that the moonwalk would begin early. We rushed back to our microphones and reported the... (MSNBC -- Technology)
IBM to forecast space weather from solar storms Jun 19, 2009
By integrating the signals from geographically dispersed 3D radio antennas, clusters of blades will issue space weather forecasts for the next 18-to-24 hours from the recent state of the Sun. This space weather forecasting capability is aimed at mitigating interference from Sun-spot Cycle 24 an 11-year cycle slated to begin this year. (EETimes)
Nanocups Brim With Potential Mar 20, 2009
The particles act the same way radio antennas do, with the ability to absorb and emit electromagnetic waves that, in this case, includes visible wavelengths. Because nanocup ensembles can focus light in a specific direction no matter where the incident light is coming, they make pretty good candidates for, say, thermal solar power. (Science Daily)
