Antenna´s name wanted - RF Cafe Forums

The original RF Cafe Forums were shut down in late 2012 due to maintenance issues - primarily having to spend time purging garbage posts from the board. At some point I might start the RF Cafe Forums again if the phpBB software gets better at filtering spam.

Below are the old forum threads, including responses to the original posts.

Hi, guys. I am Osvaldo from Banfield, Buenos Aires, Argentina. I also am ham radio, my call is LW1DSE. I´ll make a 144 MHz antenna, that here is known as "antena de esqueleto" (Skeleton antenna????) and is derived from the slot one. Does anybody know the original english name of it?
It appears to be the electric opposite from a 1/2 lambda antenna (half wave), and it is used in aircrafts(???)
Thanks all.

Hi Osvaldo
The 'antenna' is actually used just as a driven element for 2 yagis, one above the other.
The name given by the inventor was 'skeleton slot' and you are right: it is the electromagnetic inverse of a metal sheet dipole.
If you do a search under skeleton slot you should find it.
Antennas used to be made and sold by J-Beam in the UK, but I think they have discontinued the design some years ago. However, several amateur publications give dimensions for different bands.

Thanks, Nubbage. Yes, I knew it in an old spanish tv antenna handbook (written about 1951), a friend gives me 20 years ago. But I want to do one for the 2m Amateur band, beause I like uncommon antennas!!!. And also I wanted to look for any data from Google, but I did´t know the original name. I tryed with a lot of synonimous, but unfortunately the results was few.
Thanks again!!!!

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...
