Construction details
Dual-Band Yagi DK7ZB 144/430 MHz 2+2el. 40cm

Dual-Band DK7ZB Yagi antenna. Excellent for FM, SSB and satellites. Singe coax feed. It will be perfect addition to dual-bander VHF / UHF like IC-7000 or FT-857d.

The antenna is available with mount in the middle (standard) or rear (on request). In addition, the rear mounting of the antenna provides both horizontal polarization and vertical.


This is an excellent antenna for FM as balcony antenna because the vertical beam covers a very wide angle (in the 70cm band almost 180 °).
