Dear Dimitris or "superas_1988"

See earlier message below. Names are good, but the antenna is not
completely specified.


Dear "superas-1988" (presumably in Greece)
It appears from the drawing that the antenna is a wire antenna with all
wires in the Y-Z plane. It is likely that the portion above the driven
dipole is a mirror image of the portion below the driven dipole. Each
dipole has the same length and that length is specified as 0.5 WL.
Questions:
1. Is the above true?
2. What is the included angle between the driven dipole and the dipole to
its right and above? It looks as if that angle is near 55 degrees.
3. Is the length of each dipole a physical 0.5 WL or an electrical 0.5
WL?
4. What is the nature of your interest? A school project? A radio
amateur's project?
5. Is the antenna intended to be used at HF? If so, how high do you
consider the driven element to be above the earth's surface?

Regards, Mac N8TT

Dear all,

Thanks to the suggestion of Mr Reg Edwards I decided to name this
antenna D-Dimond1 (ok, I changed the name he suggested a little bit).
I would appreciate to look forward from you for any comments about the
geometry or the name of this antenna. Also, once again; is this
geometry or the name prototype?

Thank you in advance for your time


Dimitris
