Using & Wiring Antenna Traps from Amateur Radio Supplies
Our traps are designed for Do-It-Yourself (DIY) hams to build professional grade multiband wire antennas (or verticals) for their QTH or next DXpedition.
You will need a pair of traps for each band you intend to operate - except the lowest frequency you intent to operate.
You will receive a wiring guide & cut matrix with each trap purchase. This guide will give you precise cut lengths for every possible trap configuration.
You will need to buy a quality center insulator. We have numerous center insulators in stock for you to choose from.
You will need to also supply antenna wire, end insulators and coax to feed the antenna. We have all of these items in stock.
