That's correct Jim. I meant close to 90 degrees (1/4 wavelength). Some of the "big guns" do have 1/2 wave tall antennas, but most are near 1/4 wave tall.
Tnx for catching that. 73, Ron AC7AC -----Original Message----- From: Elecraft [mailto:[email protected]] On Behalf Of Jim Brown Sent: Sunday, February 12, 2017 5:31 PM To: [email protected] Subject: Re: [Elecraft] EFHW Not true, Ron. Most AM broadcast transmitting antennas are in the range of 80-90 electrical degrees (a quarter wave). Nearly all of the Class I clear channel stations use antennas that are at least 180 electrical degrees. You can see this data for any US station at https://www.fcc.gov/media/radio/am-query WLW's tower is 189.3 degrees. So is WLS. WGN is 195 degrees. WBZ uses an array of four towers that are 188.5 degrees. WIND on 560 kHz near Chicago, has an array of four 100 degree towers. The station where I worked in my home town has an array of four 82 degree towers. And so on. 73, Jim K9YC On Sun,2/12/2017 9:13 AM, Ron D'Eau Claire wrote: > Most BCB (0.5 to 1.6 MHz) antennas are 1/8 wavelength high (or less) which necessitates an extensive ground system. ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected] ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[email protected] This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html Message delivered to [email protected]
