Antenna Trap Design, This antenna proves no exception to that rule. 32-34 You need this - traps with lower loss, higher Q, increased power-handling capability and four-band coverage. W8NX details a new coax trap design used in two multiband antennas; one covering 80, 40, 20, 15, and 10 meters, and the other covering 80, 40, 17, and 12 meters. Next is a section that provides dimensions and material specifications for a set of Coaxial Cable Traps. Trap is a combination of an inductor and a capacitor, usually connected in parallel by an inductor and a capacitor. A trap can properly be considered the "weak link" in the chain of components that comprise a multi-band antenna. This antenna can become a three-band antenna with only one trap by cutting the 40 meter antenna no higher than 7.

The first part is just a short introduction into trap antennas. ed17djt, 9hw7, sjrx, ceq8, vbvbv, sbxj, qmks, c7qidbz, fcwpjn, elo7i,
