FEATURES:

The 10M4DX was designed for high performance while keeping weight, wind area and costs low. Using computer optimization techniques, we have squeezed for excellent performance on both the CW and phone. The 10M4DX is a great antenna to stack with more 10M4DX Yagis or with other HF antennas. Mechanically, CNC machined aluminum (6061-T6) ring clamps ground the elements to the boom and make assembly a snap. A hairpin type match couples the 3 kW 1: balun to the feed line. The antenna is completely DC grounded. Great effort has been put into making sure this antenna stays in the air for years to come while providing enjoyment and satisfaction along the way.**Subtract 2.14 from dBi for dBd**(Rev-083109/01)
