MFJ has two new matching network products for 80/160 meter verticals. Here is the press release I received for these interesting new products:
MFJ-2910, $299.95
MFJ-2910 improves efficiency on 160 and 80 Meters for the popular new 43-foot all band vertical antennas by eliminating SWR-related coax and unun mismatch losses.
When fed with a 1:4 unun, the 43’ antenna has a reasonable compromise SWR on 60-10 Meters. However, at 160/80 Meters it is virtually impossible to match this antenna because of the low radiation resistance.
If you are using low loss coax, you will lose much power in the coax and unun due to bad antenna mismatches. Installed at the base of the 43’ vertical, MFJ- 2910 will significantly eliminate these losses and put 160 and 80 Meters back within the tuning range of the tuner inside the shack.
MFJ-2910 includes a high-voltage insulated base tube, remote power injector with switch for 160, 80 Meters and off positions. It handles 1.5kW. Matching box is mounted in a rugged, weather-resistant PVC housing, 3Wx16Hx3D inches.
New! 600 Watts 80/160 Meter Matching Network
MFJ-2908, $249.95. Has all features of the MFJ-2910, but handles 600 Watts. MFJ-2908 measures 3Wx11Hx3D inches.
