== 7 Rules for Antennas ==
* Rule #1: Use short, high quality and thick antenna cables.
* Rule #2: An SWR below 2 is acceptable (less than 11% of power is reflected so we have much of the power available for transmission).
* Rule #3: '''Always connect an antenna to the sender''' (otherwise 100% of signal is reflected, which may kill the sender)
* Rule #4: Keep the polarization of your antennas the same way.
* Rule #5: The more dBi, the more power in one direction.
* Rule #6: With a proper antenna setup, the distance in air is not an issue if we have a line of sight.
* Rule #7: Longer is not always better for antennas. Smarter is better.
All coming from the famous [https://youtu.be/J3PBL9oLPX8 video of Andreas Spiess].
