No, it is not a kit, I developed this box for easy and fast tuning of my loop antenna. Changing the band or the frequency gives a SWR of 20 or more, so it would be difficult to tune with the QMX+ because of its SWR protection, which is a good solution protecting the PA FETs. I used a box similar to the QMX+ available from amazon. I named this loop tuning box 'SWR+' - hope to have no legal problems with Hans because of this. attached an inside picture of the device.
