<P><FONT size=2><FONT face=Verdana size=3>Caros Colegas,<BR><BR>É com emoção que
tive conhecimento da morte, ao 68 anos, do professor L. B. Cebik (W4RNL) um dos
mais importantes e brilhantes radioamadores a nível mundial quando se tratava de
analise de antenas.<BR><BR>Em boa verdade, existem mesmo aqueles que pensamos,
que são profissionalmente técnicos de alto gabarito na área e descobrimos que
estamos errados. Um dos casos que mais me marcou era o do colega L. B. Cebik
(W4RNL), uma referencia internacional quando se trata de analise de antenas e
que era profissionalmente, pois está actualmente reformado, um brilhante
professor catedrático de Filosofia.<BR><BR>João

Technical Adviser and antenna authority, passed away last week. He was
68.</FONT></FONT></P>
<P><FONT face=Verdana size=3>An ARRL Life Member, Cebik was known to many hams
for the numerous articles he wrote on antennas and antenna modeling. He had
articles published in most of the US ham journals, including QST, QEX, NCJ, CQ,
Communications Quarterly, Ham Radio, 73, QRP Quarterly, Radio-Electronics and
QRPp. Larry Wolfgang, WR1B, QEX Editor, called Cebik "probably the most widely
published and often read author of Amateur Radio antenna articles ever to write
on the subject."<BR><BR>Cebik lived in Knoxville, Tennessee and wrote more than
a dozen books on antennas for both the beginner and the advanced student. Among
his books are a basic tutorial in the use of NEC antenna modeling software and
compilations of his many shorter pieces. A teacher for more than 30 years, Cebik
was retired, but served as Professor Emeritus of philosophy at the University of
Tennessee, Knoxville.<BR><BR>One of Cebik's last articles for QST, "A New Spin
on the Big Wheel," appeared in the March 2008 issue. The article, co-written
with Bob Cerreto, WA1FXT, looked at a three dipole array for 2 meters. This was
a follow-up to their article in the January/February issue of QEX that featured
omnidirectional horizontally polarized antennas. Cebik authored the "Antenna
Options" for QEX; his last column appears in the May/June 2008
issue.<BR><BR>Former ARRL Senior Assistant Technical Editor Dean Straw, N6BV,
and editor of The ARRL Antenna Book, said, "LB will be greatly missed by the
thousands of hams he's helped through his incredibly prolific -- and invariably
proficient -- writing about antennas. LB helped me personally in numerous ways
while I worked on antenna matters at the League, always communicating with a
gentle, scholarly attitude and a real eye for detail. I'm in shock at the news
of LB's passing. May his soul rest in peace."<BR><BR>Licensed since 1954, Cebik
served as Technical Editor for antenneX Magazine. According to Jack L. Stone,
publisher of antenneX, he had not heard from Cebik for a few days and became
worried: "I called the Sheriff in Knoxville to go check on him since I hadn't
heard from him in over 5 days, either e-mail or phone, which is highly unusual.
The Sheriff [went to Cebik's house to check on him and] called back to tell me
the sad, devastating news. As his publisher of books, monthly columns, feature
articles and software/models for more than 10 years, we communicated almost
daily during that span of time. Not hearing from him for that long was unusual,
causing my concern. He was like family to me and was loved and respected by so
many."<BR><BR>In a Web posting, Cebik fondly remembered his first QSO and how
his father came to his rescue during his first contact: "I was licensed in 1954
as both a Novice and a Tech, since then you could take both exams in one session
and privileges were separate. My calls were W1APS and WN1APS. I got on the air
for the first time with a ham a couple of blocks away, an fine old timer.
However, I got key fright half way through. My dad, James S. (Jim) Cebik, came
to my rescue and finished the contact, although he had not touched key in over
20 years. Jim Cebik had been 1ATG and later W1BUK in the late 1920s and early
1930s (and wrote a few articles on his experiments). He gave up Amateur Radio
when he married in the depression years; the cost of parts were high and family
came first. In fact, he rarely mentioned Amateur Radio, and my entry was
independent via some high school comrades and a cousin. But he had not forgotten
his CW or key skills and saved me from embarrassment on that first day. I
returned the favor by renewing his interest in Amateur Radio and about 1964, he
was relicensed and obtained his old W1BUK call which he used for very many
years. He died in 2002 in his high 90s."<BR><BR>Cebik maintained a Web site,
</FONT><A href="http://www.cebik.com/" target=_blank><FONT face=Verdana
size=3>www.cebik.com</FONT></A><FONT face=Verdana size=3>, a virtual treasure
trove to anyone interested in antennas. Besides a few notes on the history of
radio work and other bits that Cebik called "semi-technical oddities," the
collection contains information of interest to radio amateurs and professionals
interested in antennas, antenna modeling and related subjects, such as antenna
tuners and impedance matching. Cebik said that his notes were "geared to helping
other radio amateurs and antenna enthusiasts discover what I have managed to
uncover over the years -- and then to go well beyond."<BR><BR>His Web site also
contains information on antenna modeling. His book, Basic Antenna Modeling: A
Hands-On Tutorial for Nittany-Scientific's NEC-Win Plus NEC-2 antenna modeling
software, contains models in .NEC format for over 150 exercises. "Since the
principles in the book apply to any modeling software," Cebik said, "I have also
created the same exercise models in the EZNEC format. For more advanced modelers
using either NEC-2 or NEC-4, I have prepared an additional volume, Intermediate
Antenna Modeling: A Hands-On Tutorial, based on Nittany-Scientific's NEC-Win Pro
and GNEC. The volume includes hundreds of antenna models used in the text to
demonstrate virtually the complete command set (along with similarities and
differences) used by both cores."<BR><BR>ARRL Contributing Editor H. Ward
Silver, N0AX, said, "LB typified generosity. He was always developing material
that was published widely. Furthermore, the quality of the articles and concepts
was always high, but the writing was such that an audience with a wide range of
technical backgrounds could understand it. His Web site is a Solomon's Treasure
of solid antenna information -- available to all."<BR><BR>Wolfgang remembered
Cebik, saying, "L. B. was an ARRL Technical Advisor, with expertise in antenna
modeling and design. I learned that I could count on L. B. to offer clear,
concise comments on any submitted article dealing with antennas. He was always a
friendly voice on the other end of my phone line when I needed to talk to an
expert, and I came to expect a quick e-mailed response to any antenna questions
that I sent him. L. B. was so much more than an antenna author, though. He was
one of the first ARRL Educational Advisors I ever had the pleasure of working
with when I became editor of the ARRL study materials. He played a key role in
helping develop the concept of online courses when ARRL began to study the idea
of the Continuing Education program; his Antenna Modeling course has been one of
the most popular offerings in the program. L. B. leaves a legacy of friendly
advice and Amateur Radio wisdom. I will miss him as a friend and as an
advisor."<BR><BR>In his Web reminisces, Cebik summed up his own life in Amateur
Radio: "My Dad was a part of my Novice beginning in Amateur Radio, and I strove
to send CW with a straight key so that one could not tell it from a keyer. He
remains a strong part of my effort. He noted that the ham spirit is to give, if
needed, the shirt off one's back to a fellow ham and to expect -- not its return
-- but rather that it be passed on to the next ham who needs it." </FONT></P>
