Antenna I have a Jennair Micro wave model JMC8100ADW This looks similer to MMV1153A. It has an Antenna that you can get to from inside the cavity by opening a cover. I broke the Antenna which was produced by Maytag. Although I bought it in2002 Maytag has stopped manufacturing this part and I can not find one anywhere. So I used super glue to join the non metallic parts and now would like to know how to install it. I can not figure it out by looking at it.

Sorry for the miscommunication. In repair lingo, the part you are referencing is called a stirrer blade. It's job is to shield microwave emissions from certain areas of the cabinet while simultaneously directing energy into specific areas of the cabinet where the emissions "bounce" harmonically and evenly throughout the cavity enhancing cooking temps evenly (ergo, "stirring" the microwaves). The actual antennae is the dome that protrudes from the magnetron and into the cavity... directly behind the stirrer blade.

OK, now that we're on the same page... you're right. That blade is NLA. Both sides should have the same reflectivity so it should not matter which side faces the magnetron. You should keep it in the same position as in the pictured link above, however.

One other thing, I've never repaired a blade in this fashion because they are definitely a critical component to the proper disbursement of microwave energy. (GE microwaves had a rash of mis-engineered blades for a few years. These blades caused a "feedback" of energy directed backwards down the wave guide and at the antennae of the magnetron eventually causing a mag tube failure.) With that being said, I don't know if or for how long the glue will hold up. If it holds indefinitely, it may allow microwaves to pass through the seams of your repair causing other problems (uneven cooking, feed back to the mag tube, arcing, sparking, etc...). I simply don't know.

Good work on the mag tube replacement, though! Looking for a career in appliance repair? :) Sorry for the miscommunication. In repair lingo, the part you are referencing is called a stirrer blade.
