Default A Cure for Those Yellow Radar Antennas - Well, Maybe...

Just finished up a little project and thought I would share. I've used denatured alcohol for a while to "de-yellowfy" open array antennas and domes. While the alcohol will lighten the plastic a few shades, it does not eliminate it. I had gotten in a Raymarine 4 foot open array from a refit, and the antenna was YELLOW, almost brown! I did the old alcohol wipe but there was one spot that wouldn't budge. I soaked a bounty paper towel in acetone and with one wipe, I saw white! Now mind you, what the acetone does is it "melts" the top layer of plastic off. I practiced on an old antenna until I had it perfected, and went on to wipe the yellow off of the whole antenna, using a procedure where I would wipe with acetone, go over the alcohol to remove excess acetone, and let dry. In about 45 minutes, I ended up with the antenna below - not "perfect", but remarkably better. You can see the former yellow where the sealant is at the ends. I finished the antenna off with a coat of nu-finish silicone wax and it's shiny. I'm sure 10 people will jump in and tell me why I shouldn't have done this, but I did search online and could find nothing to suggest that what I did will in any way affect the radar's operation.

I don't see any harm in doing this. In fact, you can paint it if you want. Just don't use a metallic paint.

this will work fine with no problems - the only thing I would have done is compound/polish the surface before the nu-finish to smooth it a bit so it gets more gloss. The acetone leaves it microscopically "rough".
