TBLNA-9K30
Loop Antenna Pre-Amplifier
The TBLNA-9K30 is a pre-amplifier for the TBMA6-P, expanding the dynamic range of the passive loop antenna. The pre-amplifier is designed for the TBMA6-P, but it can be used together with any passive loop antenna for the frequency range 9 kHz – 30 MHz. The pre-amplifier is equipped with a charger for 12 pieces standard AA NiMh batteries. A ¼” thread at the bottom of the TBLAA1 permits connectivity to standard tripods.
