How to build a coaxial trap for dipoles, verticals, and end fed halfwave antennas.
Thanks to Mike (M0MSN) for this easily-made antenna accessory that allows you to shorten an antenna for 40 meter and 80 meter use. Coaxial traps can help you install an efficient antenna into a very small space.

The coax trap will also shorten the length of the wire antenna, making it perfect for the smaller garden. In this video I show and explain how to build a trap for the 40 metre band this can be used on an antenna for 80 metres giving you both 80 and 40 metre on the same antenna.. Needed for this build: 2 metres of RG58 40 mm former (an old mastic gun tube or waist pipe) Something to drill a hole the same dia as the coax wire strippers or knife soldering iron and solder.
