There are times when you may need more gain than the standard J-Pole antenna. With twice the gain of a standard J-Pole antenna, the 2 meter Slim Jim antenna is a J-Pole on steroids! The Slim is an end-fed folded dipole antenna that has a gain of 6 dbi and a nice low RF take off angle. This makes the 2 Meter Slim Jim antenna a great solution for repeater sites, data and packet stations, APRS, and even every day communications. I like to use my Slim Jim antenna for running emergency weather nets as the increased gain gives me a nice strong signal into the repeater and also makes it easier to capture weak stations on simplex if I need to listen to them on the repeater input frequency.
