|1.5kW 80/160M high-efficiency Matching Network|
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.
Includes high-voltage insulated base tube, remote power injector with switch for 160, 80 Meters and off positions.
Matching box mounted in a rugged, weather-resistant PVC housing.
3W x 16H x 3D inches.
