hi
I wondered what would happen if lightning hit my station.
Realize that it's impossible to say exactly but in general i wonder
what the 'step' of failure would be ...
My set up is fairly simple:
I have a few J poles (stainless rods)
some dipoles around 80f some are 10ga some 14
a gps antenna
a fiberglass 900mhz and 1.2g
a 2m and 440 sat eggbeater
most are connected via lmr 400 some lmr600
preamps on the sat are cat 5 fed
one dipole has a sgc tuner fed also via cat5
straight run from roof down a concreate 2x3ft 'shaft' opens on
roof down to elec closet on my floor then into my apt
I have ICE lightning protectors (14story building i am on 4thfl)
almost near where coax enters my apt
they are 'grounded' to the elec ground which I tested and is good as
elec grounds go
typically when weather is bad i unscrew the coax going to the radios
at the ice and leave dangling this creates about a 2ft 'gap'
so assuming a worst case and my roof antennas take a direct hit
what would i theorize would happen?
I suspect the 14g dipole wire would va****ize perhaps also the 10ga
perhaps the jpole might remain?
i suspect the egg beaters would partially va****ize and their baluns
melt
the sgc would fail,
would the coax va****ize at the roof?
would i suspect (distance from roof to ICE @[EMAIL PROTECTED]
apt 175ft of coax
) the coax would carry much power measured at my apt end? or
would it va****ize first??
if not would it be absorbed by the concreate walls given the
distance? /arc? by the time it got to my apt?
assuming there would be power down to the ice and given it's
connected to elec ground would anyone suspect they would
dissipate the power to gnd? or just arc over the apt?
any general thoughts as to what might actually happen in this
scenario from both a practical and theoritical would be
appreciated
i always wonder what would be logical to assume in a direct hit
scenario
thanks
