[TowerTalk] Tribanders on separate towers

[Jack White]

Hello Towertalk 

I’ve been considering installing multiple triband Yagis (interlaced element types, say 4/4/8) at my QTH to be able to switch directions quickly or power split in multiple directions. Installation heights can be between 50-120’ and the towers are between 100-200’ apart. Some time ago ISTR Frank W3LPL saying this arrangement would need careful modelling (maybe it was on a CTU presentation) but I’ve not been able to find this information since. 

Unfortunately the towers are crank ups so a more traditional stack would be a lot more complex and prevent me from lowering the towers until I could remove the lower antennas with a cherry picker. 

Also, does anybody have interlaced type triband Yagis models that they can share?

I’m interested to hear any thoughts or experiences.

Thanks
