Antenna Build Project Posted on March 1, 2021 by Michael GrcevichMarch 6, 2021 It was great to meet the folks in West Point and our County Emergency Coordinator Sam Hernandez who guided us in making our 450 ohm Ladder Line Slim Jim Antenna (pictured above) it fits conveniently in my tactical pack. Pictured in an upright storage position the emergency antenna shows good performance on two meters and 70cm. Plus it was fun to build! Also an open stub J-pole was also available as a project.
