[Waverley ARS] RF fuse

[David Benchoam]

Hi Guys,

Just wanted to mention that Benelec sells a in line EMP protector for
lightning protection of radios. It's a Spinner product made in Germany,
capable of DC-2500MHz
N socket to N socket bulk head design. The outer of the device needs to
be well earthed. The voltage of the gas capsule is 90V so max 120W RF,
however we have capsules capable of upto 2Kw. If you refer to our web
site we have technical notes on EMP protectors (Under Technical
Articles) and how they work. Also details of the different versions we
carry.

Cost of 90V EMP is around $140 plus GST. Keep in mind these are a high
quality high performance unit. There would be some cheaper solutions
around.

Regards,

Hi All,

I am flying out in three hours. I'll try to set up a sked by IRLP or SMS
.
Canada is seven hours behind us.

Mathias, one way to protect against RF surges at the antenna end (e.g.
near field lighting flashes) is to use a gas fuse. This device normally
passes RF, however when the RF becomes massive, it ionises a gas in a
glass cylinder and routes the  surge to earth. The gas is consumed and
the gas fuse needs to be replaced.
Better the fuse than your equipment.
