I asked if anyone could identify this antenna
http://home.comcast.net/~ross_anders...ionAntenna.htm .
Mike, NZ4K, suggested I look at this site
http://www.starkelectronic.com/wing4.htm .
A close match is the Winegard CA-8098.
This is a fascinating antenna (the VHF part), consisting of two booms
coming together in a V, with the elements attached to the boom off
center, and the elements on the upper boom placed asymmetrically with
respect to the elements on the lower boom.
Now my question is: Has anyone seen this type of antenna written up in
any journal, conference proceedings, book, patent, web page, or message
board; or is anyone willing to share their thoughts or unpublished work
on this type of antenna?
Thanks, Ross W1HBQ

Yes.

Popular Electronics in the 1960s and 1970s (Ziff Davis ownership) featured a
number of articles on constructing deep fringe VHF and UHF antennas. These
designs featured a similar pyramidal profile and element configuration.

You are very lucky that I still have one of these PE issues (for another
reference article).
Look for the Popular Electronic December 1971 issue -- George J. Monser
wrote the article of interest (page 40):
"Build a Mini-Pyramidal UHF TV Antenna". He reports pulling in UHF stations
(in San Diego), that were 185 miles away.

Mr. Monser lived in the Santa Barbara, CA area at the time of the PE
article.
His article references an earlier: "Build the Pyramidal TV/FM Antenna" that
was featured in the July 1969 issue of PE.
Supposed this UHF antenna design is a trimmed down version of that earlier
VHF design.

I've tried to build antennas with this "technology" back in the 1960s. I
couldnt give you any specific referance to where design data is available.
But, it might be interesting to you to note that the stations being received
are in the direction that the Big V is pointed.
The fundamental concept is to feed the "Big V" at its "pointed end".
Then, the radiating elements get increasingly longer as the feed line
spreads. When the elements are about right for radiation at the frequency
of interest, the majorty of the signal is either radiated or received. In
addition, each succeeding element is reversed in phase. Since the VP of the
transmission line is about the same as velocity of the radiated wave from
the previous element, a Null is created in that direction (away from the
pointed end).

When I learned about the LPV antenna, I considered it to be more practical
for the TV frequencies. They work with elements 1/2 wave long and when the
elements are 3/2 wave long. That works quite well with TV frequencies.

I'd bet you can get the attention of some "real" antenna designers in this
news group to explain the Log Periodic Antenna design. I was never a
really good antenna designer and havent worked in antennas since 1969.

A point to be made: The entire propagation path betwix San Diego
and Santa Barbara is over salt water (AKA the Pacific Ocean.)
There's been many reports of Shack-On-The-Hip operators bringing
up repeaters in San Diego from Santa Barbara (and versy-vicey.)

Good tropo here is probably a bigger factor than good antenna(s).

Jonesy -

Yes

Once I found out where he lived .. that became apparent. Of course, he made
no mention of this
signal path in the PE article (impressing the teenager at that time of the
deep fringe coverage of the design).
