The antennas I made in about an hour a piece. For less than £4 each. The only thing is they have not been tested yet. Apparently using 10 awg you do not have to have a wave trap. But it does have to be 0.4mm from the plate. So this is what I come up with for 0.4mm off the ground plate. I will have to test it on all channels & bands to see which is best. Same withe the omni. I have not got a printer so I had to dig on the info to draw a former template for 5.8ghz. If anyone wants the info I'll post it.
