The Coaxial Trap, great for more than one band on a single antenna. 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.

Enjoy
I do hope you enjoy it and subscribe for more..
