Someone ( WD8CHL JIM???? ) wrote some documentation up about using a Co-linear from a higher freq on a lower freq... and angle of radiation lowered as I recall but gain did not change... It actually can be favorable depending on the site as I recall.. I think it was Jim anyhow.. forgive me if I offered a wrong author :-)...who penned some information on moving commercial colinear to amateur and some sleeving was needed bring the feed point back to 50 ohms... but no other mods were done that I recall...
