feed methods?

RE: feed methods?

Your .psd file is in a proprietary file format. Photoshop.

Not everybody would be able to open this.

It would be better to extract the same image and paste it in-line using the image paste buttons.

RE: feed methods?

The first a) is just a loop fed with balanced transmission line. Nothing complicated.

The second b) seems to be just a (thicker) loop fed at the top with coax snuck through one arm.

The diagram for b) lacks detail. At first I thought it might be a shielded loop, but on closer inspection it's not. There's a good discussion of shielded loops here, for ref. But it's not that.

RE: feed methods?

Feed b) will radiate from the outer jacket of the cable. Hence it will affect your antenna pattern. Feed a) needs a balun to make it work normally.
