Antennas : Active- PA0RDT Active Antenna
- Active antennas can be very useful, in particular they can help reduce local electrical noise by allowing the antenna to be installed in a corner of the garden well away from house wiring. The original PA0RDT antenna uses a very small patch for the antenna and relies on the antenna being installed quite high.

- Most people think it's a good thing to have and the more the better. However, this is not always true - and the amount of gain is often not what it appears to be. Assuming higher gain is what you need, how do you determine what will give the best performance?

- Near-Real-Time F2-Layer Critical Frequency Map
- This map can be used to determine the frequencies that will always be returned to the Earth. Transmitted frequencies higher than the indicated contours (which are given in MHz) may penetrate the ionosphere, resulting in lost power to space.
The map shows the radio auroral zones as green bands near the northern and southern poles.
