Would anyone be interested in trading a select-a-tenna for the following?

The MFJ-959B RECEIVER ANTENNA TUNER/PRE-AMPLIFIER is designed to properly
match your antenna to your receiver for better performance from 1.8 to
30 MHz with a single antenna.
Maximum signal power transfer occurs when the impedance of the antenna
matches the impedance of the receiver. This will happen at specific
frequencies as determined by the length of the antenna. At these frequencies
a tuner is not needed. If the antenna is used at frequencies other than the
resonant frequencies, the signal from the antenna to the receiver may be
significantly reduced due to the mismatch of the antenna to the receiver.
The MFJ-959B can transform the antenna impedance to match that of the
receiver for maximum
signal. The MFJ-959B also has a broadband transistor pre-amplifier to help
boost signals to a copyable level which is especially helpful on the older
receivers which lack sensitivity. A 20 db attenuator is also built in to
help
receivers plagued with overload problems from strong signals.
