Article on Short HF Antennas for Portable Radios

Guys,

Attached is a geeky 19 page pdf of an article by Ulrich Rohde N1UL and Kazimierz Siviak KE4PT titled “Tuning Electrically Short Antennas for Field Operation’. The article appeared in Microwave Journal May 2019, pages 104 through 126. It focuses on short antennas for HF manpack radios. It covers theory, antenna matching, tuner components, performance measurements, etc. There are many nitty-gritty comments but some are unfortunately not expanded upon. Look for comments on the hi-pass T tuner popular in Amateur radio tuners.

Enjoy.
