Ultrabeam UB-V40 8 Band Vertical, 6/10/12/15/17/20/30/40m
Just like the Yagi antennas, the vertical by Ultrabeam work with a radiator of variable length. Only that the radiator is pushed up vertically instead of horizontally. To make that work against gravity, the vertical has a smaller additional tubing inside the larger, outer glass fibre tubes. This assures the copper tape to run smoothly. The motor drive is the same as with the beam antennas, the controller is the RCU-06 with a special firmware for vertical antennas. The lower end of the motor unit has a reinforced mount which is installed on a vertical tube, either on the roof or at ground level. A 100cm long aluminium tube with 50mm diameter is supplied, the maximum diamter is 50mm.
The UB-V40 vertical has a height of approx. 11m, sufficient to house a λ/4 radiator from 6 to 40m. In conjunction with a suitable radial system you will have a very efficient and perfectly matched vertical antenna. Due to the very low take off angle this antenna is very well suited for DX work. The UB-V40 requires a 4 wire control cable. The antenna should be guyed in any case, a guying clamp is supplied, but further material like guy ropes, clamps and thimbles not is not supplied. To connect the radials the motor unit has metal rail which can take several radial wires. The coaxial connect is PL type (SO 239). The weight of the antenna is approx. 8.1 kg.
