Dear Dimitris:
Thank you for the information.
I constructed a model of the antenna with 60 degrees and 0.5 WL
electrical lengths. Please see my message called "Greek Double Rhombus" of
May 3, 2005.

Because the intended frequency is very high, disregard the comments in
my message about performance above ground. Your use is almost certain to be
many WL above ground and thus the FS pattern will be close to the pattern
attained.

The high input impedance at resonance might facilitate the use of
arrays.

Good luck with your project. Let the group know how it ends.
Regards, Mac N8TT

First of all, I want to apologize about my late response. I would like
to try answering your questions:
1. All the above you' ve mentioned are true.
2. Actually is 60 degrees.
3. Electrical 0.5 WL.
4. This will be a university postgraduate theses.
5. The antenna is intended to be used at 1111MHz. However I dont' know
how high the driven element will be above the earth's surface.

With regards
Dimitris
