The antenna you see above doesn’t really look like an antenna. When you think of an antenna, you probably think of something made of metal. You don’t think of white plastic. In fact, you might be confused, since we all know that plastic can’t receive signals. And yet, this is an antenna. There are plenty of antennas covered in white plastic, and they’re just as effective as the traditional metal ones.
You see this all the time with marine antennas, but you’ll also see it with some TV and cellular antennas designed for home use. It’s not just to keep the antenna pretty, there’s actually a good reason.
The white is often fiberglass
In the case of marine antennas, fiberglass is usually the covering of choice. It’s light, durable and transparent to RF signal. For TV antennas it’s just white plastic, which is less durable and more subject to corrosion. But, then again the sea air isn’t usually as much of a problem on land.
No matter what the material, the purpose is to keep the items inside from corroding. Antennas are commonly made of aluminum because it performs pretty much the same whether it’s corroded or not. However, some antennas may have copper elements or a mix of copper, aluminum and steel. Copper is more sensitive when it’s not corroded but almost useless when it is. That’s why copper wire is always encased in some sort of sheath.
Adding that layer of plastic keeps whatever’s inside corrosion-free and dry. It’s common sense for harsh environments, and the sea certainly can be a harsh environment.
There’s also a little bit of vanity involved, at least with marine antennas. It’s common to see a bright white leisure craft and that shows it’s clean and well maintained. A white fiberglass sheath over an antenna matches the nice white look of the boat. A lot of installers even opt for white cable when possible. That finishes out the look and keeps things looking really clean.
