Strange question.... We have a new site opening soon and have planned to use the MR46e with the MA-ANT-3-F6 antenna. Due to supply issues we have the MA-ANT-3-F6 but not the MR46e's yet , we have a handful of MR42E's free and was wondering if I could use these with the MA-ANT-3-F6 antenna. I know you are meant to use the MA-ANT-3-F5 antenna but wondered if I just didn't connect one of the 2.5/5Ghz leads on the MA-ANT-3-F6 it would still work as a 3 array antenna rather than a 4 . This is just temp solution until the MR46e's arrive.
