MFJ-270 Lightning Arrester DC-1GHz, UHF-F/F 400W by MFJ

This is good for a little insurance incase a lightning bolt gets a little to close.

Excellent quality! My SWR actually dropped .5 when I added this with a suitable ground. Beware, many of the others have a 50 watt max! This is rated at 400 watts.

Im satisfied with this product.
