Foundations Of Amateur Radio

Foundations of Amateur Radio The other day I did an experiment. I searched for "dipole calculator" and using the first 20 results I calculated the length of a dipole suitable for 7.130 MHz. I chose the frequency for no other reason that there is a 7130 DX net every Monday, Wednesday and Friday and for the longest time I've been unable to participate due to the lack of a HF antenna in my new shack. So here's some things I learnt from doing this experiment. Depending on which calculator I use, the length of my dipole can vary by over a meter from longest to shortest result. Depending on my desire to use metric or imperial measurements, my dipole will be a different length, because of course electrons move at a different speed if you're not using the metric system. In case you're wondering, 1 inch is defined as being exactly 2.54 cm, so there's plenty of opportunity to vary that. Speaking of standards, we all agree that the speed of light is a constant, right? Turns out that for some calculators, you can c
