STACKING ANTENNAS . 19AT091 14 PM 74 / M. Stacking antennas comes down to: combining two or even more than two antennas together so that they together form an Array. All the antennas in the Array are putting in the same amount of effort to achieve a stronger signal than the single individual. stacking two yagi's - eHam.net stacking two yagi's (1/2) > >> gerald horn: How do I stack two yagi antennas to double the gain?
