ECO ANTENNAS LW-20 long wire end fed from 80 to 6 meters
The LW-20 are end-fed long wire antennas. They have a 9:1 UNUN at the feed point
which allows powering directly with 50 Ohm coaxial cable. THE UNUN
9:1 also removes static noise and provides a DC path to ground. Everyone is
capable of handling up to 400W RF.
With 20m length, it will work
on all bands from 80m to 6m via an ATU. Great performance with small footprint.
These antennas give excellent results where space is vital. However, Please note that due to the variable impedance characteristic of any long wire antenna, the ATU built into the average transceiver will not be can handle all bands. For full coverage you will need a External ATU or in any case a system capable of capacitively loading the je X of the antenna. This result can be obtained with chord networks in an L-shaped configuration to T.
The LW-20 is fully assembled and ready to use. Even the thread poly weave does not tangle and is extremely durable.

Unun di scarsa qualita' e poco affidabile.
L'un-un presente è uguale ad altri simili. Bisogna capire che se si lavora con antenne con questo tipo di configurazione su frequenze dove non risonanti anche se l'accordatore porta il Rosso a 1:1,1 bisogna limitare la potenza di uscita in quanto l'antenna resta sempre non risonante e la potenza che le arriva torna tutta indietro dissipandosi sul ballon.
