We used the Smiley Antenna for the HamShield Kickstarter. Its about $25 (you might find it on sale somewhere), and it will give you all 3 bands. We did some testing on this antenna and it works surprisingly well. Much better than the rubber ducks we originally tested with.
Yes, I agree there is an issue with ongoing support and keeping the community momentum going. This has been a common complaint and I am working on fixing this.
