Dear colleagues, here is my some results for LOG antenna - to build and optimize parameters: https://ur4lrg.tech/effective-receiving-antenna-of-low-frequency-hf-ranges-ramus/ Best regards, Dima. 10 Oct 2026, 20:54:11, From "James C. Hall, MD" <[email protected]>: Question:
Do both ends of the loop connect to the same antenna post on the feed point ? Or perhaps the ground post is used ? 73, Jamie WB4YDL Sent from my iPad > On Oct 10, 2026, at 11:40 AM, Wes Stewart via Topband > <[email protected]> wrote: > > Hi Andree, > My quick attempt at modeling the LOG shows it is bidirectional and influenced > by the ground underneath it.
