The 80m Lite Trap has finally become practical due to the design using relatively thin wall polyethylene pipe, winding with RG174 coax and covering with adhesive polyolefin heatshrink. The connections use M4 stainless steel nuts, bolts, and washers. The trap measures 120mm (4.75") long by 40mm (1.6") diameter and weighs only 90grams. The inductance is 34uH and equivalent capacitance 55pF giving a resonant frequency of 3.65MHz. When used with 2.5sqmm PVC covered wire it requires 19.5m (64foot) of wire from feedpoint to trap and 10.33m (33ft 11) from trap to end of aerial at the insulator.
When using 6sqmm PVC covered wire the first part is the same but beyond the trap is 10.05m (33ft) to end. Rated for use in a Trap dipole for 200W continuous or 400W peak power on SSB.
