I am in the process of planting a 50' aluminum tree that is overkill for my hexbeam. I got the idea to put a 2M beam up there to have directional gain at my disposa1. Initially I was going to get a 7-10 element and mount it horizontal for 2m SSB. I ended up getting a Cushcraft 4218 XL "Boomer" for an absolute steal of a price from a local ham. It is an 18 element 29' long monster of a beam with 17.2 dBd of gain. I want to use it. A friend of mine and I were talking about it and we both had this thought to slant mount it at 45 degress so I can have use of it for both vertical and horizontal polarization modes, taking a ~3dB hit from either use. On the surface that seems like a reasonable proposition, could only go wrong if I try to work somebody else with a yagi slanted the other way no? Am I missing something? Just looking for some discussion on the topic. As an aside, nowhere have I been able to find an online copy of the Cushcraft 4218XL manual, the OM who sold me this one had the original manual which I have scanned and uploaded as screenshots below for perusal, if somebody comes across this thread and wants the PDF version, please feel free to email me.
