Subject:  Thanks Help! Author:  Joe T Milam <w5ua@juno.com> Date:  02-Apr-2000 19:00:46 My thanks to Natan, W6XR, Pete, N4ZR and Guy, K2AV, for helping to straighten me out on the theory behind potential interaction when stacking a 40M driven element at 10 feet above a C-19XR. The consensus is that if the Cushcraft D-40 happens to be resonant near 21MHz, aligning it along the axis of the C-19XR elements might interfere with the 15M performance of the C-19XR. Ten feet stacking separation might be enough, but it might not. The accepted way of minimizing interaction between the antennas would be to align the 40M driven element along the axis of the C-19XR boom. I will measure for resonance with a grid dipper before committing. Gentlemen, thanks for taking time to respond. I appreciate your help. CU in the pileups. 73 Joe T. ***W5UA*** Joe T. Milam 4732 W.
