Example VHF High Band Yagi

Here is the output for a five director Yagi cut for the center of the H-VHF band. This would be similar to an Antennacraft Y5713 or Y10713.

Construction is assumed to be based on a 1" square metal tube boom and 3/8" round tubing for the elements. The directors and driven element are not insulated from the boom. (The driven element is a folded dipole. Its' center point opposite the feed point contacts the boom.)

If the well is dry and you don't see rain on the horizon, you'll need to dig the hole deeper. (If the antenna can't get the job done, an amp won't fix it.)
