Up to 40 dB gain over your portable's internal AM antenna! Coarse and fine tuning allow accurate signal adjustment from 530-1700 kHz; regenerative amplifier boosts incoming signals. May be used as a wireless-coupled loop, or directly wired to the external antenna jack of your radio, or to tune a larger outdoor antenna!

    The Super Select-A-Tenna is an active device with additional controls that has an internal regenerative amplifier and requires a 9V battery (not included). The unit has an additional variable 0dB to +10dB gain added to the intrinsic +30dB for a useful gain up to +40dB. The unit has both Coarse and Fine Tuning controls for ease of operation at the higher gain settings. It also has the capability to effectively drive a remote ferrite probe. This is useful on applications of large case radio installations that the Super Select-A-Tenna cannot access directly with it's intrinsic near proximity effect.

    The Super Select-A-Tenna may be used in any of four different modes:
    (1) Direct Near Proximity
    (2) Ferrite Probe Near Proximity.
    (3) Direct Wired Antenna Connection.
    (4) External Antenna and Ground for metal-buildings when using modes 1 and 2.

    The 541-S has a high-signal level and low-impedance balanced drive port for the ferrite probe. This provides the capability to not only drive the 6 ft. coaxial cable and probe, which are included, but the cable may be extended to as much as 26 ft using extension cables readily available locally. This is very useful for remotely locating the 541-S away from radio noise sources or into better signal locations, when moving the radio itself may be inconvenient.
