Wireless TV Aerial Buying Guide

Investing in a TV aerial is as important as investing in a TV set. No matter how large the screen, how versatile its features, or how sleek its design, it is still not enjoyable to watch if the signal is weak and the picture is fuzzy because of a low-quality TV aerial. A TV aerial is actually a part of a television set, and it is absolutely necessary for home users to get one that is perfect for their TV and home set-up. There are a few types of TV aerials, from outdoor to indoor models.

People who have a signal concern in their homes or people in need of a signal for their second television may be searching for a wireless TV aerial. But what exactly is a wireless TV aerial? Users wanting this type of aerial must first know to what exact purpose they intend to use it before furthering their search. Pinpointing the right kind of TV aerial to buy becomes much easier only after clarifying the purpose and gaining knowledge about its specifications, installation, and operation.

Reasons to Look for a Wireless TV Aerial

There are a number of reasons why home users want wireless TV aerials. One reason is they want their second television to receive the broadcast from the first television in another room. Another reason is people want to wirelessly connect to a source device, such as a DVD player. These reasons create a huge problem for an individual and families, even those who only watch television occasionally. Thus, the search for a wireless TV aerial begins. Wireless TV aerials, however, is not the only term used for such devices. Wireless AV transmitters and receivers is a specific term, as well as wireless video senders.

Wireless AV Transmitter and Receiver Overview

Wireless AV transmitters and receivers allow users to transmit a signal from one television to another television that is in a separate room. This is made possible by connecting the transmitter to the first television, which has an indoor aerial or is connected to a cable, and connecting the receiver to the second television.


Typical kits for AV transmitters and receivers contain parts like an HDMI cable, two power adaptors, and four to six aerials that fit into the transmitter and the receiver. Both transmitter and receiver units have power and link LED indicators, IR windows, HDMI connectors, and power adapter sockets.


When setting up the transmitter, use the HDMI cable to link both the transmitter and the source device (set-top box or DVD player), then plug the power adapter to an outlet. As for the receiver, use the other HDMI cable to link the receiver and the television, and then plug the power to an outlet. For the transmission and reception to work properly, make sure that there is a clear line of sight, which means that there is no interference between the transmitter from the main TV or source device and the receiver from the second television.

Range of AV Transmitters and Receivers

The maximum distance between the transmitter and the receiver varies depending on the model. Buyers should consider their own needs to help them decide on a model.



2.4 GHz

Up to 80 metres

5.8 GHz

Up to 120 metres

Long range

Up to 5,000 metres

The aforementioned ranges can decrease depending on the number of obstruction—walls, doors, or furniture—between the transmitter and the receiver. The table above provides users a quick guide for the different ranges of AV transmitters and receivers.

Optimising Performance

As mentioned, for the transmission to happen, there should be a clear line of sight between the transmitter and the receiver. Transmitters and receivers that can "see" each other make an ideal transmission. A second television can still receive a signal from a main television even if there is a wall blocking the line of sight, but the transmission is less than ideal. HDMI cables, as a part of an HD-ready AV transmitter and receiver, are suitable for television sets with high-definition programming, but there are also wireless receiving AV transmitters and receivers for analogue television sets that users can buy online.

For a strong connection between the transmitter and the receiver, it is best not to put multiple devices in the same room. It is also advisable not to have a 5.0 GHz wireless LAN or a cordless phone near the transmitter or a receiver. Large home appliances, such as refrigerators and air-conditioners, can weaken the signal transmission between the transmitters and receivers.


There comes a time that users encounter a problem in picture and audio of the second television when using the wireless AV transmitter and receiver. It is important to know how to deal with them.

Picture Problems

If after setting up the AV senders, the second television still shows a black screen, check if the right channel is selected. There are television sets that have several AV channels for one or more inputs. When there is a blue screen instead of black, the television could be receiving a blank signal, so ensuring that the transmitter is operating and that each unit is connected properly to the TV or source device is an apt solution. If the monitor is showing grainy lines, it is most likely an effect of the interference from another electronic device, such as a cordless phone or a laptop computer. Make sure that there is no electronic device below the transmitter and the receiver.

Audio Problems

If a second television is showing picture but not producing sound, it can be a loose connection problem. Ensure that the transmitter and the receiver are connected properly by pushing the cables firmly into the sockets. A distorted sound coming out of a second television results from high level of volume from the source device, so turning down the volume of the source device is the best solution.

If users hear a buzzing sound, especially when the monitor is showing bright pictures or the on-screen menu, they should just change the A/B setting on the connector of the transmitter. A second television that produces a hissing sound and a low volume despite turning the TV volume level to full blast can be fixed by turning the volume of the source device or the main television, making sure that the transmitter and the receiver are within the usable range. If there is a microwave oven in the room, turn it off.

Other Reference for Troubleshooting

Aside from the basic troubleshooting in this guide, users can also consult the manual that comes with the wireless video sender kit. There are manufacturers who have an official website with pages dedicated for troubleshooting. Users may also have access to a live chat support through the manufacturer’s website. Finally, there are manufacturers who have a 24/7 phone hotline to entertain any question or feedback regarding the product.

Buying a Wireless TV Aerial on eBay

With online shops, buyers can now afford to do their shopping whilst sitting comfortably in their homes. Shopping on the online shop eBay is easy, and purchasing your wireless TV aerial only takes a few steps. Just by typing the keywords or its variations, "wireless AV transmitter and receiver" or "wireless video senders", you next see a list of different products from different sellers.

When shopping around for a wireless TV aerial, you need to consider the usable range of a wireless TV aerial in phase with your budget. Note that as the allowable distance between the transmitter and the receiver becomes longer, the price of the device gets higher. You also need to consider if the source devices, such as a DVD player or a set-top box, are high-definition devices. This way, you can search for HDMI AV senders that are apt for such devices. Make sure that the seller you are dealing with on eBay consistently receives high buyer ratings, dispatches items quickly, and has earned a track record of excellent service. The most credible sellers on eBay have a top-rated seller badge.


Users searching a wireless TV aerial can also use the terms wireless video senders. The AV units are very useful in providing signal to a second television through a main television or a source device in the house. Wireless AV transmitters and receivers also allow users to watch a DVD movie in one room even if the player is in another room. The range or the usable distance between the transmitter and the receiver depends on the model of a wireless TV aerial, but even a powerful device that provides up to 5,000 metres may have its performance weakened by interference from another electronic device or an obstruction by a wall or a door in the room. So it is important to remove all interfering gadgets or appliances and allow both AV units to see each other, if possible. Wireless AV transmitters and receivers are a perfect solution for wirelessly connecting another television to a number of electronic devices, and they are a worthy investment for people who have a second or even third television set at home or the office.
