How does antenna gain affect the strength of a signal transmitted ?
Antenna gain indicates how strong a signal an antenna can send or receive in a specified direction. Gain is calculated by comparing the measured power transmitted or received by the antenna in a specific direction to the power transmitted or received by a hypothetical ideal antenna in the same situation. If the comparison is to an ideal (text-book pattern, lossless) antenna radiating or receiving energy equally in all directions, the gain is measured in dBi (decibels-isotropic). If the comparison is to an ideal lossless half-wave dipole antenna, defined as having 2.15 dB gain, the gain is measured in dBd (decibels-dipole). Note that the decibel is a logarithmic unit, meaning a 6dB is almost four times the reference power; 7 dB is five times the reference power, etc.
Direction of the power propagation is a key characteristic of antennas. Gain is often represented in a two-dimensional plot of the radiation pattern where the radius of the plot is on a decibel scale that may be normalized to maximum value for the particular antenna, or to an isotropic radiator. The direction that has the most power is considered the main lobe, exactly opposite the main lobe is the back lobe, and any other unwanted or unintended radiation features are called sidelobes. If no direction is specified, gain refers to peak value in the direction of the antenna’s main lobe.
For example, a collinear antenna oriented east-west with 6.41 dBd gain would be able to transmit or receive more than 4 times the signal power of an ideal dipole antenna in the east and west directions. There would be very little signal transmitted in the north and south directions.
Higher gain generally means that the signal is concentrated over a smaller beam width. This might be appropriate for some linear applications, such as those that need to isolate a specific signal and avoid external interfering signals. A wider beam might be needed, for example, if there are many receiving units that move around that need to stay connected, as in police or taxi dispatchers. Different antenna types have different antenna patterns.
Dipole
A dipole antenna is, at its simplest, two straight rods or wires oriented end to end on the same axis, with a balanced feedline connected to the two adjacent ends. By itself, a dipole antenna is close to omnidirectional, with nearly equal power transmission in all directions. In addition to VHF transmissions, dipole antennas are often used in shortwave applications or as FM broadcast receivers.
Yagi (or Yagi-Uda)
A Yagi antenna is an array of dipole elements, where one dipole is connected to receive the signal, and the other elements are designated to reflect or redirect the energy in the desired direction. Yagi antennas are directional and need to be mounted facing the intended signal path. The main lobe is wide, with a somewhat smaller back lobe. This type of antenna can be mounted horizontally or vertically, depending on the desired signal polarization. Yagi antennas work well for point to point as well as multipoint applications.
Collinear
A collinear antenna array is a series of dipoles mounted end-to-end. With up to 10dBd gain, they have a narrow bandwidth and multiple side lobes. They are often used in mobile communications, such as police, fire, and taxi dispatchers.

Top 5 ways to stream video sustainably and profitably
In today’s digital age, streaming video has become a popular and profitable business. However, with the increasing demand for online video content, it’s crucial to adopt sustainable practices to ensure long-term success. Here are the top 5 ways to stream video sustainably and profitably:
- Optimize Video Compression: Use efficient video compression techniques to reduce file sizes without compromising quality. This reduces bandwidth consumption and energy usage, making your streaming platform more sustainable.
- Implement Adaptive Bitrate Streaming: Adaptive bitrate streaming adjusts the quality of the video based on the viewer’s internet connection speed. This not only provides a better viewing experience but also reduces buffering, resulting in lower bandwidth usage.
- Utilize Cloud-Based Services: Use cloud-based streaming services to host your videos. Cloud services are more energy-efficient than traditional servers and offer scalability, allowing you to adjust resources based on demand, thus reducing costs and environmental impact.
- Monetize Through Ads and Subscriptions: Implement a monetization strategy that includes both advertising and subscription models. Ads can generate revenue without directly impacting viewers, while subscriptions provide a steady income stream.
- Promote Sustainable Practices: Educate your audience about the importance of sustainable streaming practices. Encourage them to reduce energy consumption by streaming in lower resolutions when possible and to support environmentally friendly initiatives.
By adopting these practices, you can stream video content sustainably while also maximizing profitability.
How is Extron solving issues with bursty network ?
Bursty network traffic refers to fluctuations in data transmission where there are sudden spikes of high data transfer rates followed by periods of low activity or idle time. This pattern is common in many network environments, particularly in those that handle a mix of different types of data traffic, such as video streaming, file transfers, and web browsing. Bursty network traffic can be challenging to manage because it can lead to congestion, packet loss, and increased latency, impacting the overall performance and reliability of a network.
Extron has addressed the challenges of bursty network traffic with its innovative PURE3 codec, specifically designed for the Pro AV market. This codec is a key component of Extron’s NAV Pro AV over IP Series, which has been recognized for its exceptional capabilities in handling bursty network traffic. By being able to tolerate and effectively manage bursty network traffic, PURE3 ensures that video and audio content is transmitted smoothly and without interruption, even in environments with highly variable data traffic patterns.
The ability to handle bursty network traffic is particularly important in converged networks, where different types of data traffic share the same infrastructure. Extron’s PURE3 codec offers improved network resiliency, allowing it to cope with the bursty network traffic typically found in these settings. This is a significant advantage over many third-party codecs, which can struggle under similar conditions and may require costly isolated networks to function properly.
Extron’s approach to bursty network traffic not only enhances the performance of its Pro AV systems but also provides clients with greater flexibility in choosing their network architecture. Whether operating on converged or isolated networks, users can rely on Extron’s PURE3 codec to deliver robust and pristine video quality, unaffected by the challenges of bursty network traffic.
In summary, Extron’s innovation in handling bursty network traffic through its PURE3 codec has significantly benefited clients in the Pro AV industry. By ensuring reliable and high-quality video transmission even in the face of bursty network traffic, Extron has set a new standard for AV over IP solutions, offering unparalleled performance and flexibility in network design.
What is PURE3 ?
The Extron PURE3 codec patented, wavelet-based, compression technology offers improved network resiliency. The PURE3 codec tolerates bursty network traffic found on converged networks while exceeding the performance characteristics of standards-based compression systems. Others rely on delicate third-party codecs that fail when exposed to unpredictable network traffic. Those codecs require costly isolated networks, but PURE3 is the ONLY codec designed for the Pro AV industry that delivers robust, pristine video on converged or isolated networks. With sub-frame latency, PURE3 processes video signals with 4:4:4 color quantization, while maintaining the original source quality and native resolution. PURE3 Intelligent Selective Streaming is an exclusive Extron technology that leverages periods of low motion in streamed content to enhance streaming performance. The PURE3 codec also features advanced error concealment, providing high immunity to network errors such as bit errors, jitter, and out-of-order, or dropped data packets. PURE3 error concealment provides robust picture delivery without the increased latency or bandwidth typically introduced by other error correction schemes.
Error Concealment
PURE3 offers improved network resiliency that ensures reliable transmission of high-quality imagery with the ability to conceal network errors caused by bursty network traffic found on converged networks. The decoder holds image data and presents it if needed, concealing missing information. PURE3 error concealment does not increase latency or add overhead like the error correction schemes used by competitors.
