SPECTRUM 80/40m LITE TRAP DIPOLE in 2.5square mm wire for regular duty. These dipoles mark the next evolution from the original W3DZZ trap dipoles. Then developed and had manufactured a new multistrand low impedance twin feeder, then design and construction of the Lite Traps without potting and with further modified top wire lengths. The low impedance twin feeder allows differential mode signals on receive and transmit to travel along the feeder without a measurable emitted electromagnetic field. On receive identical noise is picked up on both cores giving almost no differential feeder noise at the rig. It is so quiet using this feeder that at first you might think the aerial system is faulty. This aerial has been proved to be 2 to 3 S-points quieter than G5RV aerials and others fed with 20m coax cable and/or 300 Ohm ribbon. This version is supplied with 2.5square mm cross sectional area multistrand top wires together with 21 metres of the 100 Ohm twin feeder, though greater lengths can be supplied if required. Otherwise you can use a balanced ATU such as the MFJ or the old KW Z-Match or SEM EZ Tune. The endorsement attached is typical of users of the LTD80/40m trap dipole. Experience proves it to be typically 2 S-points better on receive and transmit than the comparable G5RV. The Inverted V configuration often has better performance day and night than a straight configuration but needs to take into account ground capacitance to the outer sections beyond the traps. Otherwise resonance will be below the 80m band and this is corrected by reducing the outer sections by about 24 each.
