New Range of Automatic HF Antenna Tuning Units Defense Advancement
An antenna tuner is a passive electronic device inserted into the feedline between a radio transmitter and its antenna. Its purpose is to optimize power transfer by matching the impedance of the radio to the signal impedance at the end of the feedline connecting the antenna to the transmitter.

QRP Manual DIY Antenna Tuner Kit 1 -30Mhz. This little QRP (low power) Antenna tuner has been around for a while and it is sold as a Kit from Aliexpress, Amazon, Ebay, Banggood to name a few. The price ranges from $8.00 through to $60 (discounted for the same group of components. The design is actually quite simple, building on some existing.
LDG Z817H Automatic antenna tuning unit radioworld
An aerial tuning unit (A.T.U.) is a useful accessory for any radio listener as it matches the antennas resonant length to the received frequency, increasing gain and reducing spurious signals.
Homebrew TMatch Antenna Tuning Unit (ATU) Jet Propulsion
6 Any material surrounding the antenna with a permittivity (loosely called Dielectric constant, Dk, Loss tangent) different from 1 (air permittivity is 1, water is 80) will affect the antenna tuning. Other parameters such as the distance from those materials to the antenna and the amount will play a role into defining the equivalent effective.
Tony Allen EI4DIB, (Drogheda,Ireland). 70 MHz Antenna Tuning Unit for the 4 Meter Band by Mike
An antenna tuner acts like the transmission in your car, which selects the proper gear ratio for the work being done, such as starting from a standing position, cruis-ing at a steady speed, or climbing a hill. If the transmission does not match the right gears, there won't be an eficient transfer of power.
Antenna Tuning Unit for Medium Wave Broadcasting
Every antenna tuning unit (sometimes called Antenna Coupling Units) must be designed to conform to the particulars of the AM antenna and transmission system. We work closely with you to determine the specific requirements of your system. Some of these design considerations include: transmitter power, frequency, bandwidth, antenna impedance.
WWII ERA ANTENNA TUNING UNIT BC306A US ARMY SIGNAL CORPS Wwii, The unit, Us army
The antenna tuning unit may be used with a selection of long wire antennas like outdoor antenna and short wire antennas like attic antenna. Using this ATU will prolong or shorten antennas electrically to have a better match on the desired frequency o f transmission. Source:Antenna Tuning Unit.

Homebrew TMatch Antenna Tuning Unit (ATU) Jet Propulsion
All Rohde & Schwarz antenna tuning units (ATU) operate in the frequency range from 1.5 MHz to 30 MHz, where they tune antenna impedance to 50 Ω in both receive and transmit modes. Rohde & Schwarz ATUs also provide preselection in receive mode. HF wideband and ALE-4G (MIL-STD-188-110D; MIL-STD-188-144D) are supported as well. Quick links

1 Go to an open area free from buildings, trees, radio towers, or other structures. 2 Put your radio and antenna in the positions in which you will use them. For a CB radio, put the radio in the car and the antenna on the body of the vehicle. For a portable radio, move away from any vehicle and stand alone with the radio. 3

AM Antenna Tuning Units (ATU's) Products
An Antenna Tuning Unit (ATU) performs a simple but important function in many transmitting systems. Almost all things called an ATU are simply impedance transformers, and almost always, narrow band impedance transformers (meaning that when adjusted, they achieved the desired transformation over only a narrow frequency range).

Antenna tuning is a crucial aspect of optimizing the performance of an antenna system. It plays a vital role in ensuring maximum power transfer between the transmitter and the antenna, resulting in improved signal strength and overall system efficiency.

An antenna tuner is a passive electronic device inserted into the feedline between a radio transmitter and its antenna. Its purpose is to optimize power transfer by matching the impedance of the radio to the signal impedance at the end of the feedline connecting the antenna to the transmitter.
Homebrew TMatch Antenna Tuning Unit (ATU) Jet Propulsion
The antenna tuner DOES increase the power transferred from the transmiter to the transmission line and therefore increases the power radiated from the antenna. The antenna tuner does not reduce the portion of signal lost in the transmission line. The antenna tuner DOES NOT improve the radiation eficiency of an antenna.

An antenna tuner, (transmatch), doesn't really TUNE your antenna OR ANY PART OF IT! What an antenna tuner or transmatch does do, however, is transform the impedance at the antenna feed output at the radio to a value that your transceiver can handle, (typically 50 Ohms).
