Here's an interesting magnetic loop antenna from Peter Parker (VK3YE) when he first started experimenting with this type of HF antenna. According to Peter, this "compact magnetic loop antenna (is) capable of operation on all amateur radio bands between 160-10 meters." Although the efficiency is quite low, Peter was able to make solid contacts from his backyard with this experimental transmitting loop.
Peter says the feed line "connects directly to the copper tube which has a tapping point for the coax inner...other builders use a second smaller loop inside."
If you have restricted space for a multiband HF antenna, you may want to try Peter's antenna.
