Stan and group, I found this post and referenced video very interesting. However I am bothered by several things.
First, a multi-band antenna cannot be a “end-fed half wave” on all bands. only on one band, as far as I know. I’ve read many articles about “end-fed half wave” antennas over the years, and they have always been single band antennas with special matching circuits to tune them, and most have agreed that when they are a half wave on the frequency used, a counterpoise or radial is not required. Which leads me to question the statement that a counterpoise or radial other than maybe a one meter or less one is required for this antenna. A 30’ antenna will only be a half wave near 20 meters, what happens on the rest of the bands? I know that sometimes using 5 watts or less, you might not notice a hot chassis or RF floating around, but, what is going to happen when you load this antenna with 100 watts? I would appreciate hearing from others and what they think about the questions I have raised. 73, Bill, k6mgo ______________________________________________________________ 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
