Improved product handling and transfer apparatus includes rotatable product buckets for receiving product and re-orienting product for packaging in diverse configurations or containers. The antenna provides a low cost, physically small multi-element antenna system capable of being integrated into mobile devices and designed to form nulls in the radiation pattern to reduce interference from unwanted interferers. This measure ensures that the shear forces acting on the joint act approximately at a right angle to the bonding surface over the entire test period, so that realistic conclusions may be drawn with regard to the material properties of the tested adhesive.
