Am I correct in my thinking that when you stack 2 antennas the E-plane beamwidth is halved. In my case I'm going to stack 2 VHF beams for 2M that have a 35 degree E-plan beamwidth I think it will be 17.5 degrees after stacking them one above the other. I also think the H-plane beamwidth will not change. Am I right or wrong? Julio, W4HY
