Re: [Repeater-Builder] crackle in a repeater tower

KE4ADV     What you propose should be practice and not an experiment.  It is just good practice to ground the antenna mast, coax and equipment to a common ground.  Otherwise where I am located in West Florida the setup might last a month due to lightning.  You should also use double shielded coax or hardline for your coax run and in your equipment. 73's de Tom Manning, AF4UG ----- Original Message ----- From: [EMAIL PROTECTED] To: Repeater-Builder@yahoogroups.com Sent: Wednesday, March 22, 2006 8:33 AM Subject: Re: [Repeater-Builder] crackle in a repeater tower I am observing the same phenomenon on a 2 meter repeater in my area. You'll find it interesting that the BD-224 was just replaced, however on "windy days" the repeater sensitivity gives way to that crackling noise that you referred to. My theory, which will be tested soon, is that due to poor grounding static charges build up in the antenna due to the effects of high velocity wind. Our plan is to install grounding kits on the coax at the antenna and on the ground near the gas tube. All grounds will be at the same point as much as is possible. Stay in touch with me for the result of this experiment. YAHOO!
