In short, if you are serious about SWL, get an ATU. Co-ax Antenna Feeders - Low Loss Or Dead Loss? Coax-fed antennas have become law during the development of the latest generation of radio sets. In one corner, the radio hams talk of antennas as religion.

Antenna Tuning Units (ATU) are used as a coupling between the transmitter and antenna. These are required to achieve and maintain proper tuning for your antenna, and are used on all NDB and DGPS systems. All antenna tuning units include automatic phase matching (tuning) for the antenna system.

Jul 21, 2012 · Six Permutation ATU - peak up your SW signals for general RX. I hope this project will give flexibility to construct and design "more" on ATU's. For my General Coverage Receiver, I wish to connect an Antenna matcher or Antenna Tuning unit for getting the peak signals without images, intermode or other phantom signals.

Nov 1, 2020 · Given that the resonant frequency of the antenna would not be broad enough for the tuning range of the Belka-DX I decided to build a small antenna tuner just for SWLing. After a couple of hours searching the internet for a simple tuner I found just what I was looking for on http://www.hard-core-dx.com/nordicdx/antenna/lab/tuner.html.

Turn on your shortwave radio (mine is a Sony ICF-SW 7600G). Extend its telescopic antenna and place it near and parallel to one side of your homemade tuned loop shortwave antenna. tune-in a broadcast station within the frequency coverage range of …

The basic T-Network ATU performs reasonably well under a wide range of impedance mismatches and its adjustment can be quite straight forward if a roller inductor is employed for L.

Jul 7, 2011 · An ATU can be very useful if you are not using a resonant antenna or if you are using a resonant antenna outside its optimal band. An ATU helps by bettering the power transfer between the antenna and receiver and compensating …

Nov 23, 2024 · We have been using a JD 200 ATU for steering in 7810 and 9750 combine. My grandson saw an ATC to replace it. It is an electric motor to direct oil straight to the steering cylinders and eliminated the unit on the steering column.

We provide professional AM (LW/SW/MW) broadcasting equipment and complete turnkey solutions for AM broadcasting stations, including the sale of medium wave transmitters, 50Ω MW antenna tuning unit (input power depends on your AM transmitter power), and several high-quality AM broadcast antennas, dummy loads and other professional equipment.
