Your antenna is entirely unnecessary!
I was told this by a VK contact who claimed to be using only magnetic loop antennas because they were every bit as good as his previous Yagi and Wire types.
Hmm. I like my antennas, and put a lot of effort into making and maintaining them. Could he be right?
Well, I first went to the ARRL Antenna Book -a fine volume, and practically no use to answer this question. I don't have the new translation of "Rothammel's antenna book ISBN: 9783000624278 " (Amazon currently offers it in Russian only!) and it is so big and heavy that RSGB won't send to USA - too heavy! > Maybe it has the answer!

The Windy Hill Gang of CATS gave a fine demo of transcontinental QRP using a small HF magloop from the back of a pickup truck. No ground needed, fine clean receive signal and easy tuning of the loop for transmitting.
Do we need tall towers and long wires?
