Hold on! I am getting confused!
This is not the statement I answered to! I only challenged your quotes of "receiving gain" and "broadcating gain" as an antenna parameter, which does not exist for a given antenna. nothing more.
I also say that parabolic gain is dependant on reflector size, and I do agree with you that a parabolic antenna will outperform not only the yagis but also any other kind, depending on it's size.The "windsurfer kind doesn't fit in this category, if it can be called parabolic. When it gets to parabolic, the bigger, the better!
All I wanted to say earlier was about gain. There is only one type of gain, measured in db. Same in both directions.
As of "receiving" or brodcasting" gain, it does exist when you want to compare WIFI cards, its called "receive sensitivity" and "output power".
Will we agree on that?
PS: Do not worry! Among all my antennas, I also have a 32" parabolic dish!...
