The Ultrabeam "VL" type antennas are vertically mounted dipole loops for one, two or three elements (VL = Vertical Loop). With this construction a compact dimension is possible without giving up much of the performance of a full size antenna. So this is an excellent compromise for space and performance. The model UB640-VL-2.3 uses a switching relay to select the driven element. Please note that this antenna requires two additional control wires.
