How about a new and different HF antenna for the 2017 ARRL Field Day on 24-25 June 2017?
In this post, NC4FB offers a variation on the popular G7FEK nested 1/4 wavelength compact Marconi antenna that fits into a space of 46-feet/14.02 meters long and 24-feet/7.31 meters high. This antenna offers a low angle of radiation, covers 80 through 10 meters, and is coax-fed. An antenna "tuner" is required to optimize antenna performance.
Construction guidelines are here:
NC4FB offers his opinion on this cleverly designed multi-band HF antenna:
My friend KI4PMI and I always like to try something different each ARRL National Field Day. This year we selected the G7FEK as one of the antennas to be used during Field Day. The antenna turned out to be easy to build and after some experimentation we were able to adjust the 40 meter and 20 meter radiating elements for very low SWR operation using an AIM-4170C analyzer. The 80 meter band SWR curve was excellent without any adjustment. The other bands (17, 15, 12, 10, 6) indicated useable SWR curves but will require a good antenna tuner. We used a Palstar AT-500 manual antenna tuner to successfully tune these bands for maximum power transfer from the transceiver.
