The following analog radar
units will function with the E-Series Classic MFD's. Raymarine has discontinued the sale
of analog radar units.
I asked Raymarine that same question.... The answers that they gave are listed below. It appears that your radome is compatable with the E80.
The Key will be when the radome was manufactured.
Model numbers M92650-S or E52065 are 2KW 18" domes that are compatible.
Model numbers M92652-S or E52067 are 4KW 24" domes that are compatible.
Model number T52001-S is a 4KW open array that is compatible.
Model number T52012-S is a 10KW open array that is compatible
If the Radar unit was made prior to May of 2003 , then it is not compatible. If if was made after May of 2003 then it is compatible. Please see the following link for answer ID# 964 pertaining to radar compatibility.
