The above is a view of an Excel spreadsheet passive repeater calculator.
The calculator can be downloaded by right clicking on the link and selecting “Save Target As…”
http://www.storm.ca/~nand/990/PassiveRepeater.xls
or
http://wijnandromijn.com/990/PassiveRepeater.xls
Just clicking on the link will run the spreadsheet if you have Excel installed, with the option of saving before the window closes.

Keep in mind that the path loss in the calculator is for free-space-line-of-sight. This can only be approached on earth by having a clear and wide path between antennas.

Corrected and updated the spreadsheet. The km to mile conversion was backwards. Added a signal level calculation for the pickup antenna. This point can be measured and should give an indication how well it may work before running the coax cable. Also added a cable loss table for different cables and frequencies on sheet 2.

Nand.

excellent work!

thanks man!

Nice job

All I know is don't ever ask me to pronounce your name and get it right the first time!

Ditto on the well done calculator. Very nice.

Don't worry jim. I've been trying to pronounce it since thursday and I still haven't gotten it.

I believe the "ij" combination has gotten morphed into the letter "Y" but it can be pronounced hard as in "wire" or softer, as in "if". It depends on how you want it to be heard.

It's much easier just to say "Nand" and leave the rest alone.

Now all we need is a "Nor" and our logic would be complete !

I'll try to confuse people even more by mentioning that famous New York Van Wyck expressway. Some people say it as "wick" and others say it as "why(ck)", and even New Yorkers can't agree on it.
