With low SWR, your rig will be more efficient; you'll get more power out of
your 6 meter tranceiver and into your antenna for more DX, it will run cooler
and last longer, and your expensive tranceiver will be protected from
overheating due to high SWR.
The MFJ-903 handles 100 Watts FM and 200 Watts SSB PEP. It works with
ALL solid state and tube rigs and is perfect for home and mobile stations.
