Re: Good looking antenna...
John,
Forgive my ineptness... I plugged all the numbers into the link you gave me and got a spew of numbers out, but couldn't find anything that said.. "you can go X distance."
So I found this site...
»www.signull.com/fsc.php
And put in these numbers...
Tx Pwr 15dbm (200mw)
Rx sensitivty 89 dbm (per Tranzeo)
TX Gain 9dbi
Rx Gain 15dbi (per Tranzeo)
Tx Cable Loss - 1 db (15ft)
Rx Cable Loss - 0 db (integrated)
Signal Margin - 15db (not sure what this should be)
I was given the response...
Total Gain 120 - Max Distance 6.16 miles
Does this look/sound right?
What is a good Signal Margin suppose to be?
Thanks for taking the time on this...

It looks OK to me. The Signal Margin is related to fade...from heavy rain, for example. More is better, 20 dB is great, 10 dB is marginal, so it looks like you are right in between. Remember, that is for the maximum distance of the link...if the link is shorter, the margin improves the closer you get.

I ran the numbers after reading up on Signal Margin. with 22 dbm margin I can hit 2.75 miles.
So it looks like I am going to give the Hpol omni a try and see how it works for us.
Appreciate all the info. |
