FEATURES, FUNCTIONS AND SPECIFICATIONS:
SIGMA LW-20 HF 80-6m Wire Antenna.
At the heart of the Sigma LW range of antennas is the 9:1 UNUN.
This provides a feedpointfor the long wire radiating element and converts the impedance from 450 Ohms (+/-) tosomething nearer to the 50 Ohms expected by your transceiver.
There are three connectionson the UNUN , a SO-239 to which you connect the coaxial feed line and two machine screwswith butterfly wing nuts.
One of these has the wire antenna connected to it and the other is for you to connect a length of wire to earth.
This is not strictly a necessary connection but willreduce static pick up and provide a direct to earth for any possible lightening strike or buildup of static in the air.
The best way to do this is to attach a length of wire to a ground rod and fix it to the UNUN at this terminal.
Fix the feed point up as high as possible – it may be attached to a pole or to a wall and then attach the other end of the wire to a point as faraway as is possible.
This is best done if the wire can be kept in a straight line and horizontal but , if this is not possible due to space restriction, do not despair.
The wire may be doglegged, sloped or fixed in any number of ways to enable it to fit in a space available.
The LW-20 will operate on all HF bands from 80 m to 6 m with an external ATU.
The other end of your coaxial cable should be attached to your ATU and then from the ATUto your transceiver. Power up, make final adjustments to tune and away you go.
The LW-20 are end fed long wire aerials. They all incorporate a 9:1 UNUN at the feedpoint enabling them to be fed directly with 50 Ohm coaxial cable.
The 9:1 UNUN also removes static noise and provides a DC path to earth. All are able to handle up to 400W RF (full UK limit).
NOTE 1: Version 2 dated July 11 - 2024
The power rating is for intermittent amateur (400W CW or 500W SSB) use only, and not for AM broadcast or digital data modes (FT-x, RTTY, etc) , or constant carrier data modes.
For AM broadcast a much higher Power Balun is required.
