5 – 6 GHz Helical Antennas

Thursday, September 13th, 2007


Wow ! It’s a surprise for me to see that helical antennas are working so good on 5ghz to 6ghz band. Here is a company that selling them http://www.q-par.com/products/helical-antennas/5-6-ghz-helical-antenna

GAIN ~10 to 11.5 dBic by specification -who knows 🙂

So if You like to try 5ghz wireless links, You may try helical antennas . I’ll be waiting for results if someone try to build and test this.

Here is the picture of one of this – nothing unusual really:
