June Presentation - Antenna Coupling Units  
Wednesday 06 June 2018, 19:30 - 22:00
     

Antenna Coupling Units (ACUs) are not the same as Antenna Tuning Units (ATUs) – all you need for ATUs are side-cutters, or if you were too enthusiastic, a soldering iron.

  • Where does the ACU fit among all the other components in the total system between sender and receiver?
  • Why do we need ACUs?
  • How do ACUs work?

Brian VK2GCE will discuss these questions and then proceed to show how to design a simple ACU, the ?-coupler. This will include consideration or power, frequency, Voltage and current on the ACU’s components.

If you are offered an ACU that is alleged to handle 1 kW, you will learn to ask:

  • at what frequency
  • at what output impedance
  • to match what range of antenna impedances
  • at what cost.

The St George Amateur Radio Society will be gathering for the regular monthly presentation in the meeting rooms are at Donnelly Park, Kyle Parade, Connells Point - near South Hurstville. The gathering starts at 7.30pm.

After the presentation, there will be the usual refreshments. All members, local amateurs and others interested are invited to attend.
