LW-20, Multi-band Long Wire Antenna 80 - 6m
Now Mk. IV
Long Wire Antennas - The LW range
These are all end fed long wire aerials. They all incorporate the M0CVO 9:1 UNUN at the feedpoint enabling them to be fed directly with 50ohm 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.
LW-20: 20m in length, this will work on all bands from 80m - 6m via an ATU. Big performance from a small footprint.
These antennas give excellent results where space is at a premium. For full band coverage you may need an external ATU or possible some form of capacitive loading system. This can be a simple L or T match.
