In my models, I've also noticed that the F/R suffers when the antennas are stacked. However, I've been able to re-optimize the element lengths based on the stacking distance and height above ground a

Bill, I have been using a three stack of SteppIR's for one year in configuration close to what you plan on planning. Mine are stacked at 33, 66 and 100 feet on a 100 foot R55 rotating tower. The top

Terry, I have two 4 El's. One at ~85 and the other at ~45 ft. I do much what you do. I tune individual antennas for best SWR and then switch to both. Woks well on all bands but 20. My top antenna is

Hi Howard, Thanks for the replay. Does the Comtek switch work better than the Stackmatch? What I see here is the lower and mid antennas have flat SWR when running standalone but when I put them into

Terry, I have both the Comtek and Stackmatch. I used the Stackmatch first and found the same thing I am seeing now with the Comtek. I stayed with the Comtek because the Array solutions did not have t

Terry, Look carefully at the design of ANY stacking switch. Many use a single fixed 2:3 turn radio autotransformer (2.25:1 impedance ratio) as a compromise for both two antenna and three antenna stac

Hello Bill, I'm switching a two stack of 4L SteppIRs - 132 and 100 ft. Use a homemade stackmatch plus that has BOP. First SteppIR accessory to get is Larry's, N8LP, SteppIR Tuning Relay boxes for eac
