If you’re serious about antennas, you might be considering a tower in your backyard. Antenna towers make it possible to put your antenna high above roofs and trees. Remember up to 90% of your signal can be blocked by common objects like houses. So, a tower is a great way to make sure that you’re getting the best possible signal.
Towers are more common in rural areas of course, where people have plenty of room to put one up. An average person probably doesn’t need to put a tower much higher than 50 feet. However, there are cases where you need to go higher than that.
You might even need to go so high that you need to think about obstruction lights. An obstruction light is the light that goes at the top of your tower. You’ve probably seen them on tall buildings and antenna towers as you drive by at night.
Why an obstruction light is needed
Obstruction lights are placed on tall objects so that low-flying planes can see them at night. You may not think that you’re in any sort of flight path, but it doesn’t matter; obstruction lights are required on every tall thing. It’s not just a tower or a building. In some cases obstruction lights are required on power lines, monuments, basically anything tall that stands by itself.
How high does your tower need to be before it needs an obstruction light?
The FAA rules are clear. Any object that rises to 200 feet above ground level needs an obstruction light.
There are different requirements for different lights, too. Here’s some information lifted from the FAA:
|L-810||Steady-Burning – RED||Single Obstruction Light|
|L-810||Steady-Burning – RED||Double Obstruction Light|
|L-856||High-Intensity Flashing – WHITE||Obstruction Light (40 FLASHES PER MINUTE)|
|L-857||High-Intensity Flashing – WHITE||Catenary Light (60 FLASHES PER MINUTE)|
|L-864||Medium-Intensity Flashing – RED||Obstruction Light (20-40 FLASHES PER MINUTE)|
|L-865||Medium-Intensity Flashing – WHITE||Obstruction Light (40-FLASHES PER MINUTE)|
|L-864/L-865||Medium-Intensity Flashing Dual – RED / WHITE||Obstruction Light (20-40 FLASHES PER MINUTE) Obstruction Light (40 FLASHES PER MINUTE)|
|L-866||Medium-Intensity Flashing – WHITE||Catenary Light (60-FLASHES PER MINUTE)|
|L-885||Low-Intensity Flashing – RED||Red Catenary Light (60 FLASHES PER MINUTE)|
|L-866/L-885||Medium-Intensity Flashing Dual – RED / WHITE||Catenary Light (60 FLASHES PER MINUTE)|
Of course, consult with them about the specifics of what you may need for your situation, but this table can give you some idea.
