I came across a great article on the design of short vertical antennas for 160M. Thought I'd share it.

I realize this post is coming up on 9 years old, but I need the article. The website has some kind of security/encoding issue and neither of my browsers will connect to it. If anybody has a copy of the article and is willing to email it to me, please let me know. Thanks. K5WLF

Years ago, Jerry Sevick W2FMI, the same fellow who wrote the book on Transmission Line Transformers, wrote a series of articles, in Ham Radio Magazine detailing  his work and measurements on short vertical antennas.  One of his creations was a vertical, about 8 feet tall with a top hat.  I worked him on 75 meters a few times and he had a fine signal.  Part of the secret..and it's really no secret, was that he had a textbook ground radial system in his back yard, either 50 or 120 full length radials.  A vertical will work, sorta, with a crummy ground system, but a good one makes life fun.  Down at the bottom of the Sherwood Engineering site he has an article detailing some work he did with chicken wire screen in various configurations as a low band ground.  I have used that and it works nicely, but I have a 90 foot Tee vertical that doesn't need as much help.
Short story, put more work into the ground than you do above the ground if you want to use a vertical antenna.

All of Jerry Sevick's articles were in QST from 1971 through 1981. None, as far as I can tell, were ever published in Ham Radio Magazine.

Here's Jerry diddling with one of his short verticals.

CEBIK was prolific in articles on Antenna Design.
Here is a sight containing nearly all his work.

He did publish one article in Ham Radio in November 1989 page 70 on a 10 meter Quad for portable use.
