Background and Intro
The Hamshield was a Kickstarter that ended sometime last summer. The original expected delivery date was October of 2015, but due to issues with manufacturing and a problem with their amplification circuits, it was delayed. I won't go into the details here, but you can read it on their Kickstarter page:

I've been in process of building and testing a dual-band 2m/70cm antenna for several weeks now. Recently, my antenna fell and it came time to rework it. A friend of mine was kind enough to loan me an MFJ-269. During the tweaking process, it's convenient to be able to just keep track of SWR values over the bands as well as a place for notes and changes to be marked for each test. Maybe you'll find it useful.

One of the things that we take for granted given our connected society is radio. It is strange how something invisible has had such a visible impact on our world and our culture. For the past 100+ years, radios have been conceived, built, improved, and now exist in everything from satellites to home security system window probes. They carry entertainment as well as troops orders. At any given moment, hundreds of communications from all around us are likely passing, unbeknownst, right through us.
