    nice video! linear loading is another way to shorten the dipole legs, and that will not lower the bandwidth

      @@PatAutrey linear loading. I’ll have to look into that. Thanks Pat!

    You make a valid point. I’ll try and include both in future videos. I appreciate the suggestion.

    ? I see the Calculator for inductance, how do you know how much inductance you are looking for , or targeting to build .

    • @propagating-radio

      The K7MEM site will calculate needed inductance based on the length of antenna you're aiming to build. If you then take that inductance number, you can use the inductance calculator to get your turn count based on the diameter of your coil form.
      I hope im explaing this in a way that makes sense.

    I read somewhere that the high q is a result of using small gauge wire, and thicker wire has higher a. Would this work for close comms less than 10 miles away?

      This should work well out to about 300 miles or so. You may be right about the thin wire and high Q.

    Please use the Metric System. There are 206 countries around the world. Liberia uses the Imperial system. The United States has been changing to the metric system for years.
    The rest has already evolved.
