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

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.

You do not need to use the provided lug. Home Depot sells copper lugs that will fit 6AWG wire for grounding. This will protect your equipment from lightning related surges. Came just as described

Its perfect for hams to ground their antenna shield to help prevent damage to their radios. It safely discharges static electricity caused by the wind or nearby lightning strikes. If you get a direct hit by lightning there isnt anything made to protect your rig. I have one for each of my antennas.

I cannot attest to the ability of this product to protect against all surges, however, we have had some pretty severe storms and the radio is still operational. Also important is that Ive experienced no noticable insertion loss which was a concern. Ill definitely add more when additional antennas go up. The little bit of added peace of mind goes a long way.

The name of the product may be overly ambitious. It probably cant stop a lightning strike from doing damage. It can, however, drain off the high impulse voltages produced by nearby lightning. It should be placed close to a ground rod, connected to the rod by heavy-gauge copper wire. Cut the coax and put a PL-259 connector on each side. Screw them onto the SO-239s on the lightning arrestor. Installation finished. You can feel a little more comfortable, but still remove the antenna cable from the radio during thunderstorms.

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

Lightning Happens. Youll wish you had one of these, properly-grounded, on you antenna lead-in.

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 arrested has some weight to it. I am positive that it will do the job.

As advertised.
