I'm guessing it is way too late but I'd like to point out the location of antenna in Earl is not really optimal for actual handheld use in landscape use. In landscape use when standing up I think you are typically holding it like a book and not very inclined to the horizontal. So the antenna will be pointing out 45 degrees or less to the horizon and signal will be attenuated. It would be great if the antenna was mounted truely on the side edge with the ability to tilt up to 90-degrees from the horizontal.
For paraglider and other pilots such as myself this will also be a problem - we typically have our instruments mounted on a "flight deck" that is not inclined a lot to the horizon - imagine being in a hammock with a book on your lap, or laying on the beach with a book on the sand. The antenna will probably be at 30-degress to the horizon most of the time. Again an edge mounted antenna with a swivel in two axes to support portrait use and incline to the horizon adjustment would be great.
Another use might be mounted on a bike, or other moving vehicle - when power output is limited antenna "trimming" can be very important. Something for Earl #2 maybe?
