Hi all,
I have done a spreadsheet for the calculation of Yagi-Uda array of
loops. You can get it on internet at
http://home.citycable.ch/monde-meilleur/index.html
Sorry it is in french, a direct link to the page where the spreadsheet reside is:
http://home.citycable.ch/monde-meill...antennes1.html
It is 2 versions, the original one for gnumeric at
http://home.citycable.ch/monde-meill...adres.gnumeric
and another one for excel at
http://home.citycable.ch/monde-meill...multicadre.xls
I have tested the excel version only with openoffice (I use linux at home) and it worked.
I have done a TV RX antenna on 487.25 MHz with just a few wood stick and some coaxial cable. It took me 2 hours of job, and I was able to receive with the color a channel I was just able to receive in black and white and a lot of snow with the biggest Wisi UHF antenna.
Such an antenna can outperform any commercial antenna. It will just become bigger as you get down in frequency. As example, a five elements 27MHz will do 9.5 meter length for a diameter of the active element of 3,89 meters.
Any comments are welcome.
I will appreciate very much If someone can take a look on my English and correct it. Just drop me a word or two.
Dominique
