Hi!

I want to design and build a log periodic for DVB-T and I've found
'LOGPERIO.XLS', a calculation program in Excel format.

Anyone tried this or have experiences with it?
All comments and suggestions are welcome!


Thanx,

Luc

....of course it had to be UHF...

When nobody else comments, I do.

Yes, I actually bult several LPDAs from the LOGPERIO
calculations and they work perfectly

Caution:
Each LPDA has certain Z variations over the
whole frequency range.
1 : 1.7 is very well done.....! 1:2 is still good.

Do you have the LOGPERIO version with the
antenna graph display?

Hi Helmut!

Many thanks for your comments.
NO, I had the 'default' version, in which I'd made some layout changes,
but I really like your version much more!

Thanks for sharing your experience - now I will certainly try one
(although building antennas also gives lots of fun!).

As soon as I will have one completed, tested and installed (for DVB-T
use, called 'Digitenne') I will leave another message sharing my
experiences.
