Surge from Surge Suppressor
Surge from Surge Suppressor
(OP)
What kind of Surge is coming from Surge Supressor connected to the Radio Antenna ?
2/0 downconductor has to be installed from the Surge Supressor to the ground.
The problem is - one section of 2/0 insulated ground conductor ( inside PVC conduit) has to be installed through the Hazardous Area.
They installed before couple times that conductor inside Hazardous Area but ... I don't know is it a right solution ?
I don't know - Can that type of the SURGE make ELECTRIC ARC or not ?
THANKS

I don't quite understand your question. Are you referring to a lightning arrestor - that you mount in series with your coax as it enters the building from the antenna? Lightning arrestors ground the instantaneous voltages that may occur if lightning hits the antennal

A 4-0 conductor looks reactive (Usually Inductive) at frequencies above 400 MHz. This is why wide copper strip is used in broadcast facilities. Replace or augment the 4-0 with a 4" wide copper strip and make the run to the ground as short as possible.
Check out Harger for grounding (www.harger.com) for lightning protection equipment and supplies.
Good Luck

You can modify your profile to include your signature

You sure about that?
Although noise from lightning can interfere with LF/MF/HF over huge distances, once one reaches VHF and above, lightning is rarely (if ever) mentioned as a source of interference.

One thing I forgot to mention is that little can mitigate damage from a direct strike. I was a bit tired when I posted last night. I had to drive a tower crew to the site just before sign-off, and back after the Nitrogen leak in the 6" line was identified. The Thiokol Spryte wasn't all thet Spry last night, and I don't sleep all that well in the transmitter building.

If lightning contained significant energy at Ku-band, then these same satellite TV systems would drop sync for several seconds with each lightning bolt - and they don't.
