Anyone out there with 2.4GHz #antenna experience who can help me with this helix antenna?
I tried building the #iceconefeed by DO8PAT, but I can't seem to get a good VSWR at 2.4GHz.
I tried moving and bending some parts that I though affected the tuning, but the dip at 2.174GHz stays pretty much in the same spot.
Also any pointers to literature about these types of antennas are highly appreciated.
