5 Ghz omni antenna, as is written on pictures – Bi-conical antenna for 5ghz.
Will be interesting to build and test one of this – there is no diagrams for this one but I am happy to find out schematics and undercover pictures for this one.
Only similar antenna for wifi is discone antenna.
Scaling this antenna to 2.4 ghz band will be easy too.
will be interesting to hear what You thing about this wifi antenna?
