I¡¯ve been following the thread on lightning with great interest having had the shack struck by lightning twice. As I result I have the following theory and I would like the ¡°experts¡± to look it

Powering up the 7000
New member today. Anyone running a linear amp with the 7000? Would like to run it up to 250 watts - not finding much on the internet specific to myissue.

Re: [IC-7000] Lightning Protection References
Very bad practice. The separate ground rods should be BONDED together, preferably with wide copper strap. Your installation provides plenty of area for voltage differences. Someone also said they used

I replied directly to Chuck originally, in keeping with prior my off-list recommendation, but it should have been to the group I think. Since I replied via the web form, I don't have the original

Re: [IC-7000] Lightning Protection References
Steve: I see what you're saying about the potential being uniform (it all comes up to the same potential), but the current would be mostly common-mode. A direct strike would generate mostly

Re: [IC-7000] Lightning Protection References
My ground is setup where all the gear goes to a grounding strip to a single 8 foot ground round, and then the antenna is grounded to a separate 8 foot ground rod (via) a lightning arrester Brian

Bob, My comments are embedded below. In the past, this group's moderator has suggested that long threads not directly related to the IC-7000, be taken off list or pursued on a more appropriate

Re: [IC-7000] Lightning Protection References
My shack in Maine is a wood outbuilding and the inside fuse box is about 10 feet from my equipment. Just on the other side ?of the wall is the outside meter and there is a heavy braided wire buried

Re: [IC-7000] Lightning Protection References
Chuck, I disagree that most of the lightning energy flows down the outside of the coax shield. If a dipole antenna is in the discharge field of a flash, both elements will receive similar coupled

Re: [IC-7000] Lightning Protection References
For my shorting plugs I use 2" x 0.06" copper strap with SO-239 chassis receptacles mounted on it. Drill a hole just large enough for the center pin on the back and also for the mounting ears. Screw

Re: [IC-7000] Lightning Protection References
Is there a way to make or build a grounding system to attach the antennas into when leaving the rig(s) in lightning season? Like, make a ground wire with SO-239's and banana type plugs, and plug all

Re: [IC-7000] Lightning Protection References
Clete: Yep, textbook examples of letting what energy gets to your radio result in current through it. Not so strange about the damage from the AH-4 control line. Need to treat that just as you would

Re: [IC-7000] Lightning Protection References
Jon, The problem with unplugging everything is after a while, you tend to forget. Unplugging the coax from the tuner protects the radio, at the expense of the house, since even a nearby flash can
