Has anyone got any simple moderate gain construction ideas for
antennas on the 23cm (1296MHz) band. Gain of a few dB in either
vertical or horizontal polarisations are wanted. Brief accurate
description of materials, construction sizes in metric dimensions and
tuning tips would be most appreciated, along with anticipated gain
figures/VSWR/return loss/input Z if known.

I'm not after the quad 36EL array designs, just whips, small yagi's or
dipole sugestions.

This site looks like it has some good info. Check out quagi antennas,
it is pretty easy to build high gain antennas .

Hi Marcel,

A somewhat unknown antenna, with reasonable gain and easy to
construct is the trihedral reflector antenna (corner radar reflector
as antenna). It uses a monopole as radiatior.

A short acticle (Spanish) with a photo of such an antenna can be found
at: w3.iec.csic.es/ursi/articulos_gandia_2005/articulos/RP1/350.pdf

A long investigation (English) with a high gain trihedral antenna can
be found at: http://yu1aw.ba-karlsruhe.de/shorten3dcra.pdf.

I've built one of these simple antennas , except I used copper clad
board for the reflector.

I also used a simple corner reflector for years, but I can't find any
construction details on the web.

Thanks guys,

This is the sort of general info I was after.
