Loading Coils-Let's make short or compact 20m Dipole with MMAMA

If you need a full performance dipole antenna but lack the space to erect the total lenght of this antenna, then a few suggestions from the "DX Commander" (Callum--M0MCX) will prove useful.

Callum shows how to reduce the length of your HF dipole antenna by using loading coils.  If your coils are properly made, your shortened dipole antenna will deliver almost the same performance as a full-length dipole antenna.

Here are few ideas from Callum:

"Brief discussion about loading coils, how to model them, how to use an inductance calculator and discuss narrowing your SWR bandwidth due to too high an Inductance. Here's the link: http://www.66pacific.com/calculators/.... Cheers, Callum."
