I'm thinking about putting together an Echolink link node on my local repeater frequency so I can participate in the weekly net when out of town. This seems straightforward as it's simply:
Being in an HOA, I have to try and keep my house from looking like an antenna farm / porcupine, so I thought "why not a panel antenna?" I figure I can build the elements out of 10AWG solid wire and place it on a vertical surface outside my house, paint it with leftover house paint, and it should be nicely unobtrusive.
Is there a reason not to build a biquad for such a purpose? Is there a better (less observable, easier to build, ...?) antenna for connecting from one known point to another?
I considered a simple dipole, but there's no good way to mount it and I have rain gutters on the side of the house that faces the repeater. A biquad, being relatively flat and vaguely directional, seems like an ideal solution to this particular task.
