The Green Bay Packers vs. Philadelphia Eagles game on Monday Night Football may face broadcast issues due to a contract dispute between Disney (owner of ESPN and ABC) and YouTube TV. Fans can still watch the game via NFL+ streaming or over-the-air antenna, which are effective alternatives to cable or streaming services affected by the dispute.
The article highlights the construction and operation of the ALMA telescope in Chile, a powerful radio-astronomy observatory composed of 66 antennas that work together to observe distant cosmic regions, with recent maintenance and weather challenges discussed.
MIT researchers have developed a shape-changing, reconfigurable antenna using metamaterials that can adjust its frequency range by stretching, bending, or compressing, enabling versatile applications in communication and sensing without complex moving parts.
A large 12-inch Z-Wave antenna, the Home Assistant Connect ZWA-2, significantly improves smart home device connectivity over long distances, such as in gardens and attics, by using Z-Wave Long Range technology. It is easy to set up, enhances network stability, and is especially useful for connecting low-powered sensors and devices in remote areas of a property, despite its conspicuous size and appearance.
Tablo's new DVR and antenna bundle is currently on sale for the first time on Amazon, offering a 15% discount. Priced at $109.95, down from $129.95, the bundle includes a DVR with new features and the ability to be used without a monthly fee. The Tablo DVR allows users to watch, pause, and record live broadcasts from an indoor TV antenna and a selection of free streaming TV channels, with 128GB of onboard recording storage. It is compatible with various devices and offers over 40 additional channels compared to a TV antenna alone, all without any subscriptions or hidden fees.
Physicists at the University of Otago have developed a new form of antenna for radio waves using a small glass bulb containing an atomic vapor. The antenna, enabled by atoms in a Rydberg state, offers superior performance with high sensitivity, broad tunability, and small physical size. It eliminates the need for multiple antennas to cover different frequency bands and can be accessed via laser light, making it useful in defense, communications, and satellite technology. The portable design allows for field testing, and the researchers believe it will make quantum sensors more robust and cost-effective for real-world applications.
There are multiple options available for streaming local TV channels for free, including traditional methods like using an antenna or subscribing to cable or satellite services. However, there are also alternatives like cable TV replacement streaming services and network apps that require a paid TV login. Additionally, there are free options like Fox Local's suite of apps and LocalBTV. Different streaming devices, such as those running Google TV, Roku, or Apple TV, offer various features and app support, making them suitable for different user preferences.
NASA's Voyager 2 spacecraft, launched in 1977 to explore far-away planets, has finally made contact after communication was lost two weeks ago due to a wrong command. The spacecraft, which is over 12 billion miles from Earth, sent a "carrier signal" indicating it is still operational. Engineers will attempt to turn the antenna back towards Earth, but if unsuccessful, they will have to wait until October when the spacecraft's onboard software resets its direction. Voyager 2's twin, Voyager 1, remains NASA's most distant spacecraft at 15 billion miles from Earth.
NASA has announced that its Voyager 2 probe is currently unable to communicate with Earth due to a misalignment of its antenna, which has been pointing away from Earth for over a week. The probe, currently 32 billion kilometers away, is expected to recalibrate its position in October. This glitch does not affect Voyager 1, which is still in contact with Earth. Engineers are working to resolve the issue and extend the probes' working lives.
A cord cutter shares five pro tips for optimizing antenna reception: 1) Position the antenna high in a room or near a window for better signal; 2) Avoid placing the antenna behind the TV or near electronics and metal objects that can cause interference; 3) Consider using an amplifier to boost weaker signals; 4) Place the antenna as high as possible to overcome obstacles; 5) Choose the right antenna, and if needed, opt for an outdoor antenna for better reception. Additionally, using a DVR can enhance the antenna experience by allowing for streaming and recording of shows.
Researchers at ETH Zurich have discovered a new mechanism for creating efficient nanoscale light sources by placing a semiconductor material outside the tunnel junction. By experimenting with the placement of tungsten disulfide, the researchers found that the semiconductor acted as an antenna, absorbing and re-emitting the energy created in the tunnel junction. This unexpected positioning resulted in improved light emission, although further improvements are needed. If successful, these nanoscale light sources could be a thousand times smaller than the wavelength of the light they produce, opening up new applications in data transfer and other technologies.
By using a software-defined radio and a meteor beacon, it is possible to detect meteors by reading their reflections. Practical tips are available for those who want to try it themselves, and a gallery page is available to see what a detected meteor looks like. Using commercial transmitters may not be as easy as it sounds.
Netflix's crackdown on password sharing has led to a significant increase in account sign-ups, according to data from analytics firm Antenna. The company saw the four biggest days of US sign-ups in the four and a half years it has tracked this data, with an average of 73,000 new memberships during each of the four days. While account cancellations also rose in that period, sign-ups far outpaced those figures. Netflix started cracking down on account sharing on a trial basis in Latin America before implementing the new rules in several other regions.
Netflix saw a surge in new subscriptions between May 25 and May 28, with an average of 73,000 daily signups and 100,000 new daily subscribers joining the streaming service. This comes after the company put a stop to users sharing their passwords on May 23, with over 100 million people accessing Netflix content by using borrowed passwords. Netflix's solution is to force users who share an account outside the same home to pay an additional $7.99 a month to watch, while limiting the number of additional members that paying customers can add to their account.
Netflix saw a surge in subscribers in the US after notifying users about its paid sharing policies, according to data analytics company Antenna. The streamer added 100,000 subscribers on both May 26th and May 27th, more than it gained during the covid-related lockdowns in March and April 2020. Netflix's new password-sharing policies require subscribers to pay an extra $7.99 per month to share their account with up to two people outside their household. Despite warning investors about a "cancel reaction," Antenna says there were still more signups than cancellations during the period it tracked.
