The new Ultra Beam VL 1-3
is a full size 3 ele. dynamic beam on 10, 12, 15, 17 and 20 meters and a folded dipole on 30 and 40 m.
The total length of the glass fiber elements is 11 meters. The Ultra Beam VL 1-3 utilizes three Motor Units driving a Variable Reeling System sliding up and down inside a telescopic fiber glass tube acting as a full size 1/2 wave element on any frequency in the range of 7-50 MHz. An optional 50 MHz kit (not included) must be added for proper operation and best performance for receiving and transmitting on 6 meter.
The Antenna Controller equipped with a triple motor driver board and dedicated powerfull software will match the 3 ele. VL 1-3 instantly to 50 ohm coaxial transmission line. You can also select a 180° direction reversal or bi-directional mode and it will adjust in a few seconds
Motor Unit of the driven element does have an integrated efficient high power 2:1 Balun
By applying extremely strong and telescopic fiberglass tubing and the special construction of the folded dipole, the antenna can withstand large wind strength.
All prefabricated control cables have multi-pin IP-68 waterproof connectors and do not require extra sealing. To be ordered separately.
