General Information
For new antenna installations (DXE-MBVE-5AE-RT or 5AERT8), the antenna is installed as
previously out lined in this manual. Additional clamps and hardware are included for mounting the
MFJ-998RT Remote Tuner. The mounting method for this remote tuner is outlined in this section
of the manual.
For an upgrade to an existing DXE-MBVA-5/5A (as shown in the chart above), the parts in the
upgrade kits are installed as outlined in this section of the manual. These MFJ Remote Antenna
Tuner Add-on Kits for the DXE-MBVA-5/5A 43 Foot Multi-band Vertical Antenna are made for
using the MFJ-998RT 1500 Watt remotely mounted automatic tuner which will greatly enhance the
operating capabilities of the 43 foot antenna system.
Now you can have full performance 160-10 meters with no mismatch coaxial cable loss. A Bias-
Tee from MFJ is included with the MFJ-998RT remote tuner for supplying the +12 Vdc power
through the coaxial cable from your radio shack to the remote tuner.
