Many antenna systems do not require this protection. They are shunt fed which provides a direct-current short across the feed line at all times.
Chokes may work fine, but all chokes have some parasitic capacitance across the windings which means they have a series resonances somewhere across the RF spectrum. At those points the choke will greatly disturb the impedance presented to the rig and absorb RF, even to the point of catching fire! 73, Ron AC7AC -----Original Message----- From: elecraft-boun...@mailman.qth.net [mailto:elecraft-boun...@mailman.qth.net] On Behalf Of hawley, charles j jr Sent: Sunday, September 09, 2012 6:29 AM To: k6...@foothill.net; elecraft@mailman.qth.net Subject: Re: [Elecraft] Antenna static charge precautions - any tips? Which begs the question...why isn't a 100K across the antenna jack in the original design? BTW, I use a choke across the antenna leads.
