Kelemen Trap Dipole Antennas are high-quality, heavy-duty pre-assembled wire antennas intended for permanent installations. They feature special traps made with of PTFE (Teflon®) …

A trap antenna uses L/C parallel tuned circuits to provide multiband dipole antenna that effectively switches between bands automatically. The input impedance on each of the design bands will …

A coaxial-cable trap dipole antenna installed in the attic provides a surprisingly effective solution to HF operation on the 10, 15, 20, 30, 40, and 80 meter amateur bands at a QTH with …

Feb 21, 2025 · The Pacific Antenna Dual Band Trap Dipole kit provides a lightweight, portable trap dipole. Available in 20+40M and 17+30M versions Approximately 30% shorter than a full …

Build a Space Efficient Dipole Antenna for 40, 80 and 160 Meters. Fig 2—The improved coaxial-cable traps use two layered windings to provide an unusually high inductance-to-capacitance …

Dec 11, 2024 · A “trap” is a parallel-tuned circuit consisting of a coil and a capacitor. The circuit presents at high impedance at the resonant frequency. Inserting traps into a dipole element …

For multiband applications, you’ll often find the trap dipole and the parallel dipole. Traps are tuned circuits that act somewhat like automatically switched inductors or capacitors, adding or …

Trap-dipole advantages include reduced size, instantaneous band-switching and a standard dipole radiation pattern. Traps serve as inductive loading below their resonant frequencies, so …

A trapped dipole relies on parallel tuned traps to ‘disconnect’ the additional wire when used on the specified band. The antenna described here is for operation on 40 m and 80 m.

The Hari W-210 multiband trapped dipole antenna is precisely engineered to cover the 10, 15, and 20-meter bands efficiently. Its design can accommodate up to 200 watts for SSB and CW …
