Amazing performance of ARRL 40-10 EFHW on WARC Bands

According to Dave Casler (KE0OG), the recently introduced ARRL 40m-10m end fed halfwave antenna has some additional qualities for those who enjoy experimenting with antennas.

With a few modifications, this antenna can be used on the WARC Bands without much loss in performance.  Dave discusses some of these alterations in the spirit of getting more from an antenna designed for only a few amateur radio frequencies.
