how good is this kind of antenna?
Patch antenna is Better than dipole antenna
Just noticed that's for wifi , must be 2.4GHz .. If gain is less then its not useful
Its this for
5.8Ghz Freq
with gain of: 11dBi
200mW transmitters
As I know for 5.8GHz CL and SPW famous around in the fpv world. I might be wrong but I saw somewhere it has 19db gain. Markus on RCG has good knowledge of all these. Can make antennas as per order and given channel.
