end-fed half-wave antenna for the 7 or 10 mhz amateur bands for portable qrp
FLAT EH antenna band 10 MHZ
Much of the low band HF is full of clicks and other strange noises. I began to listen to 10 MHz and found lots of activity and interesting stuff to listen to. At that time I used a 42 metre long wire fed into an ICOM AT-180 tuner and my transceiver was an of ICOM-7000. Although I had not had many QSOs on this band I was intrigued and quickly decided to construct a quick and easy flat EH design, not the EH cylinder design
