I would suggest adding a note to that wiki page.
RJ suggests that you get better reception if the antenna is pointing up. When I did my SSRs I put them in the top with the antenna up, but when you close the case the antenna is pointing down. I turned them around last season, but with one of them the wires were to short to do this and I had to desolder and put new, longer wires in place. Not a big deal, but anyone starting from scratch could avoid this.
