TV to TV Sender Buying Guide

In an age of convenience and high-tech home entertainment, many homes now come with more than one television. Today, one finds televisions in kitchens, home offices, bedrooms, and even bathrooms. The main television, usually located in the living room, is where the satellite or cable television box is located. In the past, in order to receive cable or satellite television in more than one room, there needed to be a set-top box in each room. This extra installation required cables and wires, and of course the set-top box itself. Having a TV in every room proved to be expensive. Now, with the advent of the TV to TV sender, a television signal can be transmitted from the main television to the other televisions. The TV sender allows each television to receive the same television transmission wirelessly without all the additional expense involved in buying and installing set-top boxes in every room.

This convenience has made the TV to TV sender very popular. In order to make an informed decision when selecting a TV to TV sender, the buyer should know the differences between low-definition and high-definition TV to TV senders. It is also important that the the buyer is mindful of some of the TV to TV sender’s limitations. Buyers can find TV to TV senders at local electronics shops, electronics departments in department stores, and online. However, eBay offers what must be the widest selection of wireless TV senders.

How a TV Sender Works

To make an informed decision when it comes to buying a TV sender, the buyer must first understand how a TV sender works. A TV sender is connected to the main television by way of a SCART socket. The SCART socket is the largest socket located on the back of the television.

The receiver is plugged into the secondary television by way of its SCART connection. Once connected, the secondary TV is able to receives radio signals transmitted from the TV sender connected to the main television in the other room.

With a TV sender, the user can view the television signal on two different televisions in two different rooms. The receiver can also send a wireless signal to the TV sender, commanding it to perform specific functions, such as changing the volume. This is only possible through the use of an infrared sensor on the receiver. The remote control for the main television can be used with the receiver from the secondary television. The remote control is pointed at the infrared sensor on the receiver. When the user pushes the volume button, a signal is transmitted from the secondary TV to the TV sender on the main television. It is important to source an additional remote control as this avoids the user having to take the remote control with them when they move to another room to watch television.

Types of TV Senders

There are two basic types of TV senders: low-definition and high-definition TV senders. Each transmits in a specific frequency range: 2.4 GHz or 5.8 GHz. The different frequencies are transmitted by radio waves through the use of an antenna attached to the sender and receiver. The frequency range determines the overall quality of the transmission signal of the sender to the receiver.

Low-Definition, 2.4GHz

A low-definition, 2.4 GHz TV sender is more affordable than a high-definition, 5.8 GHz TV sender. It is more affordable, because it is used to link standard televisions. The low-definition, 2.4 GHz TV sender’s television picture may be fuzzy or difficult to view due to frequency interference caused by other devices in the home. Such sources could include baby monitors, WiFi, and anything that operates with a 2.4 GHz frequency.

High-Definition, 5.8 GHz

A high-definition, 5.8 GHz TV sender is more expensive than a low-definition, 2.4 GHz TV sender. The high-definition, 5.8 GHz TV sender employs a relatively new form of technology that is still evolving. It is more expensive because the signal output and picture are clearer, and the range of transmission extends further than a low-definition, 2.4 GHz TV sender's transmission range. This newer technology allows several high-definition devices like Blu-ray players to connect to the TV sender rather than just one device. An HDMI splitter is required to connect the television and the high-definition sources with each other. With this setup, there is little interference from other radio frequencies as is the case with the low-definition, 2.4 GHz TV sender.

When there is interference such as with 5.8 GHz cordless telephones, the user can change the specific channel within the frequency band to a channel other than the one used by the cordless telephones. Both the TV sender and receiver broadcast frequency channels should be the same. With the high-definition, 5.8 GHz TV sender, the transmission signal can extend up to nine metres, depending on the thickness of walls. This extended range of transmission is made possible through a remote control extender.

Remote Control Extender

A special feature of a high-definition, 5.8 GHz TV sender is a remote control extender. The remote control extender requires a base unit and an extender unit to operate. The base unit is positioned in the room with the primary television. The extender unit is positioned in the room with the secondary television. When the remote control transmits signals to the extender unit, they are carried wirelessly to the base unit.

If the transmitter on the extender unit does not make line of sight contact with the remote control sensor, the base unit located in the other room may not receive the command transmission. Batteries are also not strong enough for effective transmission between base unit and extender unit. Both units need to be plugged into a wall outlet or other compatible power supply.

The following table illustrates some key differences between the two basic types of TV senders. The differences are in the areas of transmission range, signal quality, and cost.

The table above highlights the key features of low-definition, 2.4 GHz and high-definition, 5.8 GHz TV senders. These are generalisations only. The buyer needs to keep in mind that the signal's transmission may be affected by other radio transmitting devices like cordless phones, baby monitors, and the home WiFi network. Less frequency interference means better picture quality.

Limitations of TV Senders

Along with these positive aspects, there are some drawbacks to using the device. The buyer should be aware of these issues so that they can make an informed purchasing decision.

Multiple Senders

When a buyer purchases more than one TV sender, it is important to remember that the TV senders may transmit signals on the same frequency band. This can cause signal interference between the TV senders, resulting in poor picture quality. The buyer should select different frequency bands for each TV sender.

Channel Transmission

The transmission of television signals through walls is an important aspect of the overall operation of a TV sender. The signal, though, cannot transmit multiple television channels at a time. Only a single television channel can be transmitted and watched on both televisions at one time.

Buying a TV to TV Sender on eBay

eBay offers a wide selection of quality TV senders, including low-definition 2.4 GHz TV senders and 5.8 GHz, high-definition TV senders. They come in pairs as sender/receiver, and most descriptions also list device compatibility with other electronics such as DVD players, and satellite/cable TV receivers. To shop for a wireless TV sender on eBay, the buyer should go to the eBay homepage and type in 'TV sender' into the search bar. The buyer is then be directed to a page of listings for TV senders. The buyer can sort the listings by eBay top-rated sellers only. These sellers have earned high praise from previous buyers and scored high feedback ratings in the areas of consistent quality customer service and delivery of goods.

To sort the listings based on these ratings, the buyer should select 'eBay Top-Rated Sellers' under the Seller' heading. This sorts the listings accordingly. It is also important to know if the seller accepts returns. The buyer can find all this information in the seller’s profile. If they have any questions about the TV sender posted for sale, the buyer can contact the buyer by clicking on the contact link, which they can also find in the seller’s profile page.


A TV sender is an affordable and no-fuss solution to the problem of connecting all the TVs in a home to the household's primary set-top box or DVD player. With a TV sender, there is no need to run cables from room to room. The buyer can now watch clear audio and video reception on any television in the house from the comfort of any room. The buyer should keep in mind that the high-definition, 5.8 GHz TV senders provide less signal interference and better picture quality than the low-definition, 2.4 GHz TV senders.

The buyer is also limited by channel selection when using TV senders. Only one television channel can be viewed and transmitted at a time. Currently, there are no solutions available for this limitation. However, one should consider this to be only a minor limitation that does not detract from the convenience of being able to watch the same TV programme on two different TV screens in two different locations in the home. Buyers can find a wide selection of TV tuners as well as set-top boxes and other receivers on eBay.
