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

Price and available

used on my HAM radio antenna system

Have this mounted in a junction box near where my antenna coax enters the attic. Crimp connector for the ground wire was easy to use, even with just a pair of needle nose pliers at my disposal. Hope Ill never need to use this, but definitely feel a lot better just having it!

Have not had any problems TX or RX on 2 meters.

Product was as ordered and delivered on time.

A little pricey but solidly built. Nice fit and finish. Hopefully it offer some protection to the radio gear. I still disconnect the antenna from the radio during storms as it is unlikely this would protect in the event of a direct lightning strike.

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

I hope the MFJ-270 never gets to be tested. I am placing two of these for each antenna. One at the base of the antenna and another at the back of the house. Hope to cut down on EFI along the coax. Trying to cut down on noise returning to the Ham Shack.

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.

This product is designed to bleed off static charges. As the packaging states, this product will not protect your equipment against a direct lightning strike. Be sure to follow electrical codes and safety measures.
