1. [Amps] 2 more questions-- electrical (score: 1): Author: Charles Harpole <k4vud@hotmail.com>; Date: Tue, 5 Apr 2011 06:56:25 +0000; 1. Is it possible for the shack ground via a couple of earth implanted ground rods to be a "better" ground than that on the breaker box? (The one with a 3 foot steel rod.) 2. If you have a battery op; /archives//html/Amps/2011-04/msg00156.html (10,307 bytes)

Anyone who has run QRO and used only electrical grounds gets RF burns to the lips on a mic, to the underside of the forearm on the corners of chairs; /archives//html/Amps/2011-04/msg00163.html (12,232 bytes)

You do NOT need an RF ground at your shack in any way. The only grounds; /archives//html/Amps/2011-04/msg00166.html (11,445 bytes)

Re: [Amps] 2 more questions-- electrical (score: 1): Author: "Sam Carpenter" <sam@owenscommunication.com>; Date: Tue, 5 Apr 2011 11:50:45 -0400; I have always (almost?) run either balanced antennas with Baluns (yagis-dipoles). My problems happened on 75 mostly with phased sloper arrays, corner fed delta loops, and flat top 75m dipoles at 80'; /archives//html/Amps/2011-04/msg00168.html (12,830 bytes)
7. Re: [Amps] 2 more questions-- electrical (score: 1): Author: Paul Manuel <k4pdm@yahoo.com>; Date: Tue, 5 Apr 2011 09:01:49 -0700 (PDT); I run a 400-foot inverted vee, fed with ladderline. The ladderline comes to a balun within four feet of my mic and rig. No RF problems or RF in the audio with a kilowatt output. I also have a Hustler; /archives//html/Amps/2011-04/msg00172.html (7,034 bytes)

Re: [Amps] 2 more questions-- electrical (score: 1): Author: "Gary Schafer" <garyschafer@comcast.net>; Date: Tue, 5 Apr 2011 12:03:52 -0400; Of course you can have RF in the shack from direct radiation off the antenna. Your house wiring can pick it up and get it over to your mike as well as having an unbalanced antenna system. 73 Gary K4F; /archives//html/Amps/2011-04/msg00173.html (14,610 bytes)
9. Re: [Amps] 2 more questions-- electrical (score: 1): Author: Jim Brown <jim@audiosystemsgroup.com>; Date: Tue, 05 Apr 2011 09:47:00 -0700; RIGHT! Back to Charles's question about which ground is better. The answer is that it doesn't matter -- ALL MUST BE BONDED TOGETHER, which makes them effectively in parallel. In addition to lowering; /archives//html/Amps/2011-04/msg00176.html (11,745 bytes)

This is an NEC requirement. In general I have ground rods near the cable entrances with the lightning suppressors attached. These are bonded via ground at the water met; /archives//html/Amps/2011-04/msg00183.html (11,260 bytes)

Even the super strikes, or positive lightning will not vary much outside that r; /archives//html/Amps/2011-04/msg00184.html (13,639 bytes)

A typical strike "a mile away" may induce over 1000 volts per meter in a conductor. That distance is important. If it can do that from a mile away, think; /archives//html/Amps/2011-04/msg00186.html (10,320 bytes)
