RF ammeters - direct reading or remote reading - are used extensively in AM broadcast antenna arrays. In most cases they are available off-the-shelf but cheap they are not. I'm sorry that I don't have a convenient URL to point you to but check the sites of AM BC transmission equipment suppliers. -- 73 de K2ASP - Phil Kane Elecraft K2/100 s/n 5402 ______________________________________________________________ Elecraft mailing list Home: http://mailman.qth.net/mailman/listinfo/elecraft Help: http://mailman.qth.net/mmfaq.htm Post: mailto:Elecraft@mailman.qth.net This list hosted by: http://www.qsl.net Please help support this email list: http://www.qsl.net/donate.html
