[MLB-WIRELESS] ...the morning after.

[Dan Flett]

I'm pretty much the highest point in my immediate area, I just installed
lightning arrestors the other day.  But I haven't earthed them yet.  Is
it good or bad to have unearthed lightning arrestors?  I'm guessing that
I'm receiving some protection but I wonder what happens to the lightning
discharge if something hits?

As for 10.10.128.1 - I'd love to visit - does anyone in outer eastern
have LOS to Taylors Lakes? :)  Us here in RGSouthern have a very nice
cluster of our own thanks very much, and Kahless is an honorary member.

I know, it's just that now that I have my setup installed and running 24
x 7
and connected to Ryans box, I still feel the need to tinker and modify.
I'm
not really concerned about getting hit by lightning, as about 30 - 40
meters
away there is a very tall light pole for the footy ground behind me.

 I've got the ACA cabling manual so I can look it up if I ever decide to
do
it. Maybe I'll just put up a web cam like I was going to do in the early
days (but it costs money) or maybe some chritmas lights are in order :P

 Oh, and Ryans box is the Best place on Melb wire and is worth a visit
10.10.128.1 - plug plug plug - get on there are join the forums. Go
outer
eastern!

Howdy All...

Just a thought on the earthing of poles and equipment, you really dont
want
to earth your equipment if your not the heighest point in the area, it
may
in fact be a very very bad thing as your providing a good path to
ground,
and if lightning is in your area rather than going for a moist tree, it
will
go for your equipment... and simply unplugging it wont stop 100,000 -
1,000,000 V's jumping a air gap onto the next good earth in your
rack/pc...

If your going to earth, do it properly, 8mm earth is the minimum, but
what
you really want is a properly setup earthing grid and flat 2mm copper
strip
to conduct and a gas arrestor on the coax...

There is a lot of australian standards of earthing for electrical and
telecommunications, visit standards.com.au and have a look see (must be
in
pdf somewhere!)

Just a thought, and sorry to hear of your bad weather... it was another
lovely tropical Brisbane day here...
