Lightning Protection of Ship Communication Tower

thread247-77035

Lightning Protection of Ship Communication Tower

Lightning Protection of Ship Communication Tower

(OP)
Hi all,

From what I've heard, there was no lightning arrestor at ship's communication tower. Is there any harm on radio antenna/equipment for not installing lightning protection of about 24m height communication tower onboard ship which stationed offshore?

RE: Lightning Protection of Ship Communication Tower

"Is there any harm... ?"

None at all....until lightning strikes.

www.polyphaser.com is a good starting place.

RE: Lightning Protection of Ship Communication Tower

I read somewhere once that ship's masts on the ocean resemble a nice pointy thing on a flat plane.

Ideal for attracting lightning.

I think I'd use some lightning protection.

RE: Lightning Protection of Ship Communication Tower

Also, a typical ship is ideal for installing lightning protection.  You've got a good ground (the salty ocean) and you've got metal bulkheads (walls) to provide shielding (like a Faraday cage).

RE: Lightning Protection of Ship Communication Tower

It would be useful to install in-line lightning arrestors in each coax coming down from the antennas.  You use arrestors rated for the frequency and RF power on the line, but otherwise the tower is probably a pretty good lightning rod as it is.
