7 Element VHF High Gainer

By VU3NSH

The 2m 7 element Yagi antenna is a perfect beam antenna with 11dB gain and a front-to-back ratio of 20-25 dB. It has seven elements and requires a matching network built of 3/8 aluminum tubing and RG-8 cable. The gamma tube is adjusted to provide the best fit, and the gamma-driven element feeding clamp is tightened. If the beam is vertical, a non-conducting mast is utilized to prevent detuning and skewing of the radiation pattern. For optimal VHF operating, the antenna is installed at a height of 30 feet or higher.
