My chimney is brick, about 22 years old and in good shape. I currently have an R/S heavy duty chimney mount (metal straps, racket tightened),a 5' 14g mast section, small TV rotor with a 5' 14g section atop it. There is a Scantenna LP beam and a ST-2 (omni)currently on it.
My goal is to have one devoted 800 yagi (12 el)(AR2 800 preamp T biased), 1 450 yagi (3el), the general coverage Scantenna LP(AR2 wide band preamp T-biased),and a VHF omni gain (GAM TG5s) and possible an Austin Ferret (AR2 wideband preamp). The beams should point in the same direction,the rotor can handle the wind load. I don't have the chimney dimensions. It is a 2 flue - only one of which is used as we don't use our fireplace. I use Commscope LMR400 equivalent to Stridsberg amp'd multicouplers.
Can this be done with 2 chimney mounts? While I'd like to tower mount most of this, the tower is 200' ft from the shack, so NG.

BTW the pre-amps are appropriate given my low noise level, no intermod, and distance to cell towers etc
