40m Trap. 7.1MHz Lite trap pair for 80/40m dipole. Made in Dorset UK

A pair of 7.1MHz traps to make an 80/40m trap dipole as a descendant of the W3DZZ trap dipole. The 40m 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 90mm (3.55") long by 40mm (1.6") diameter and weighs only 65grams. Suitable for use in 80/40m trap dipole running full UK legal limit of 400W. The inductance is 15.3uH and equivalent capacitance of 33pF giving a resonant frequency of 7.1MHz. When used with 2.5sqmm PVC covered wire it requires 10.05m (33ft) of wire from feedpoint to trap and 5.53m (18ft 2) 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 5.36m (17ft 7) to end. Carriage is tracked and insured within UK and to Europe. 7.1MHz Lite trap pair for 80/40m dipole. Made in Dorset UK" is in sale since Tuesday, February 21, 2017.
