Note that my price includes standard shipping in the CONUSA. The MFJ-959B also has a broadband transistor pre-amplifier to help boost signals copy able level which is especially helpful on the older receivers lack sensitivity. If the antenna is used at frequencies other than resonant frequencies, signal from to receiver may be significantly reduced due mismatch of. It looks like one knob was replaced at some point.
The MFJ-959B RECEIVER ANTENNA TUNER/PRE-AMPLIFIER is designed to properly match your antenna receiver for better performance from 1.8 to30 MHz with a single. Check my listings for other vintage electronics. The MFJ-959B can transform the antenna impedance to match that of receiver for a maximum signal. A 20 db attenuate is also built in to help receivers plagued with overload problems from strong signals.
This is a very clean unit. Maximum signal power transfer occurs when the impedance of antenna matches receiver. This will happen at specific frequencies as determined by the length of antenna. At these frequencies a tuner is not needed.
Dont miss rare DX due to signal power loss between your receiver and antenna.
