Jerry's articles on vertical antennas and their ground systems were some of the most useful ever written on the subject. I used to have a pile of antenna books by my bed for reading at night, and his works were always among them. He used his knowledge to help others in practical ways. Wish we had more of that today!
Thank you WDCX for keeping us informed on Jerry Sevick. What I readily see is that he is, like you say, an important member of the radio community, and now I'll be collecting whatever can be found of his literary work. Links may already exist here on the site, but this would be the time to add as many more links as might be out there. It appears he left us an inheritance.
First I searched Jerry Sevick on the general web by using Start Page, and found a long string of links pertaining to Mr. Sevick's extensive publications on short verticals, ground radials and baluns. But so far on part15.us the name "Jerry Sevick" brings up no links. I think that's just about to change.
I remember his articles, too.
