An Excellent Dual Band Yagi for 50/70MHz with 2.1m boom

The 4-6-8 Dual Band Yagi has a total of 8 elements, 4 elements are used on 70MHz while 4 elements are used on 50MHz. The 4-6-8 Dual Band Yagi stands aside from the crowd due to the methods used for its design.

It is made with 1/2inch centre elements and 3/8 inch outer elements (70MHz elements are one piece 1/2inch). Boom to mast brackets are included with the antennas which will support 2 inch masts. Boom is 1.25inch square 16SWG aluminium.

The antennas are constructed with the best quality materials in order that the best mechanical construction can be achieved, even a digital caliper is used (with an accuracy of .01mm) to measure the elements during production.
