"I have been a licensed amateur radio operator since 1963 and once I discovered HS4 I thought I had died and gone to Ham Heaven. In 55 years of over the air radio I never could put up a tower with a beam antenna. On HS4 I have my choice of a number of wonderful antennas and I love being able to use these. Jump on HS4 and you will have the time of your life. 73. Jan, WA8LIS, Chicago"
