WebThe Multi-Band Trap Antenna 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 be such that a tuner will not be needed when going from one band to another. Web16 feb. 2024 · Big Wires – A 160 / 80 / 40 Meter Multi-band Antenna February 16, 2024 By Gary Rondeau Top Band, as 160 meters is called, presents a a challenge because the long wavelength leads to large antennas. One can always play tricks with loading to be able to use a physically shorter length of wire.
