8 element wideband 50-50.5MHz OP-DES (Opposing Phase Driven Element System) Yagi

The antenna has a flat SWR curve covering 50.0-50.50MHz at 1.1:1 SWR. The super 8el has incredible rearward suppression and a huge punch too

The OP-DES is the newest in patent technology and is specifically designed for maximum performance, wide-band applications. It uses the latest in Electromagnetic Design Technology to ensure the very best results and the OP-DES Yagi is proof of that!.

It is made with 5.8inch centre elements and 1/2 inch outer elements with the OP-DES end sections 3/8 inch. It has fully insulated elements which will ensure continuous, high performance for many years to come. Boom to mast brackets are included with the antennas which will support 2 inch masts. Boom is 1.75 inch (44.45mm) square 10 SWG aluminium (3.2mm wall).

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.
